Question

A 2 kg body is sliding up an inclined plane of angle 30 degree find the work done by the force of gravity in moving 1m

Answer 1

heyy here is ur ans...☺

work done = f × d

f = mg = 10 × 2 = 20N

d = 1m

cos = 90° - 30° = 60°

so w = f × d × cos

= 20 × 1 × 1/2 (value of cos 60°)

= 10J

so the work done is 10j u can put g = 9.8 also but it doesnt matter...
hope it helps u......if it did plzz mark me brainliest......thanks...☺
