okay...just help me in knowing my mistake
30-40= -10...U had written 70..
so the resulting answer will be -1000N...
it should be -30-40 because initially it was moving towards right and then towards left so we need to take tge sign
But in the solution page it was -1000N...
Actually I know how to solve option a but I don't know how to solve option B...so that only I had post this question...
Anyway thank you so much to teach me how to solve option B question....
