Technically, all of the options are incorrect, as Statement 1 is false and Statement 2 is true.

It should be E first statement is incorrect while second statement is correct.

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.

statement 1 is falsewhereas statement 2 should be true

Ans 10:

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

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 12:

Sarbari Pal from DPS FARIDABAD, Faridabad
Class : Class 5
all the options are incorrect as statement 1 is false and statement 2 is true.so the answer should look like:(iv)none of these

Ans 13:

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

Friction not always opposes motion, it opposes the relative motion but they should've given examples of it. I have read it in a book but there is no examples there, too. :-?

Ans 16:

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 17:

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

Ans 18:

Paarth Vashistha from Kunskapsskolan Gurgaon , Gurgaon
Class : Class 8
Statement 2 is correct while Statement 1 incorrect as frictions is defined as a force which opposes motion and it would not be frictional force if it is not opposing motion that why there has to be a option E.

Arnav Gangwar from DPS NOIDA, GAUTAM BUDH NAGAR

Why dont they update the answers and options?? THERE SHOULD BE A NEW OPTION HERE

Ans 22:

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
