Subject :NSO Class : Class 8
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:
Class : Class 9
Ans 2:
Class : Class 9
No statement 1 is correct where as statement 2 is also correct
Ans 3:
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 4:
Class : Class 9
Statement 1 is false while Statement 2 is true
Ans 5:
Class : Class 8
statement 1 is falsewhereas statement 2 should be true
Ans 6:
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 7:
Class : Class 8
Why dont they update the answers and options?? THERE SHOULD BE A NEW OPTION HERE
Ans 8:
Class : Class 9
I agree with ANUBHA MAHAJAN as friction does not always oppose the motion.
Ans 9:
Class : Class 9
YES THERE IS A LOT OF ERROR IN THE OPTIONS
Ans 10:
Class : Class 9
It should be E first statement is incorrect while second statement is correct.
Ans 11:
Class : Class 5
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 12:
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 13:
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 14:
Class : Class 5
Ans 15:
Class : Class 9
But friction always opposes motion...then how are they saying that option c is true?
Ans 16:
Class : Class 9
Ans 17:
Class : Class 8
You
Ans 18:
Class : Class 7
Technically, all of the options are incorrect, as Statement 1 is false and Statement 2 is true.
Ans 19:
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.
Ans 20:
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 21:
Class : Class 8
IT 'S ANSWER SHOULD BE D?
Ans 22:
Class : Class 5
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.
