300J of work is done in slinding a 2 kg block up an inclined plane of height 10m. Taking g =`10m//s^(2)` , work done against friction is

100 J

200 J

300 J

Zero

Text Solution

Verified by Experts

The correct Answer is:

Work done against gravity = mgh =` 2 xx10 xx10 = 200 J`
Work done against friction = (Total work done – work done against gravity) = 300 - 200 = 100J.
