The work done against gravitational field in raising a body of mass 2 kg from a height 3.0 m to 5.0 m, taking `g= 10 m//s^(2)`, is

A

40 J

B

60 J

C

100 J

D

320 J

Text Solution

Verified by Experts

The correct Answer is:
A
We have, m=2 kg
h=(5-3)=2 m and `g = 10 m//s^(2)`
Work done against gravitational field
`W = mgh = 2 xx 10 xx 2 = 40J`
