Read the given statements and select the correct option.
Statement 1 : While drawing a line on a paper, friction force acts on paper in the same direction along which line is drawn on the paper.
Statement 2 : Friction always opposes motion.

A Both statements 1 and 2 are true and statement 2 is the correct explanation of statement 1.
B Both statements 1 and 2 are true but statement 2 is not the correct explanation of statement 1.
C Statement 1 is true and statement 2 is false.
D Both statements 1 and 2 are false.


I don't understand how statement 1 is true

Ans 1:

Anshuman D from MVM, Hyderabad
Class : Class 8
It should be E first statement is incorrect while second statement is correct.

Ans 2:

Ananya Gupta from DPS EAST, BANGALORE , Bengaluru
Class : Class 5
statement 1 is falsewhereas statement 2 should be true

Ans 3:

Yash Bindal from Global Indian International School, Singapore
Class : Class 9
Friction always opposes motion but while drawing a line on a paper, the frictional force acts in the opposite direction in which the tip of the pen acts / the line is drawn. I think all options are incorrect as 'statement 1' is wrong but 'statement 2' is right

Ans 4:

Ankit kumar Jha from Ryan International School, Ghaziabad
Class : Class 8
YES THERE IS A LOT OF ERROR IN THE OPTIONS

Ans 5:

from Prudence, Delhi
Class : Class 4
In my opinion statement 2 is true and statement 1 is false as friction always opposes the motion of an object. Also the friction between the pencil and paper should be exerted in the opposite direction.

Class : Class 4

Ans 7:

Riya Singhani from BVB vidhyashram, jaipur
Class : Class 8
IT 'S ANSWER SHOULD BE D?

Ans 8:

Ethel shiju from National Public School Indiranagar, Bangalore
Class : Class 9
But friction always opposes motion...then how are they saying that option c is true?

Ans 9:

ANUBHA MAHAJAN from LOTUS VALLEY INTERNATIONAL SCHOOL, NOIDA
Class : Class 10
not in all cases friction opposes, this is proved from statement 1 as friction acts backward on the paper and it will act forward on the direction where the pencil is moved

Ans 10:

Shlok Ghadekar from Tomoae school, Amravati
Class : Class 8
All the options must be incorrect as friction always opposes motion and friction acts in direction opposite of force applied but there is no option saying this

Ans 11:

Yash Bindal from Global Indian International School, Singapore
Class : Class 9

Ans 12:

Amazing Kids from DPS Panipat Refinery, Panipat
Class : Class 8
Yes , I also agree that friction always opposes motion and the following options are incorrect as *Statement 1* is incorrect and *Statement 2* is correct. There is surely some error.

Ans 13:

Vidush from Dav pakhowal Ludhiana, Ludhiana
Class : Class 9
No statement 1 is correct where as statement 2 is also correct

So, for an experiment you need multiple values for comparison. This question states that the experiment is to be carried out for four days, meaning that you need to compare four different scenarios. The first one is obviously hot and windy. The four scenarios- hot, windy, calm and cloudy must be paired with each other forming these- hot and windy, hot and calm, windy and cloudy, cloudy and calm- option B

A ship is made of iron but still it floats in water. This is because of its shape. A ship is hollow in the middle. When it is in water, the entire volume of the ship, including the hollow portion displaces water to make space for itself. The volume of water displaced is much more than the volume of iron in the ship. Therefore, the ship floats in water.
In the above passage, the floatation of ship is being described with ______ principle.

A Newton's
B Archimedes'
C G auss'
D Both A and B
