Question

a stone of weight 4N in the earth gravitational field is moved from P to q and then to R along the path shown how much potential energy does the stone gain​

Answer 1

Answer:

potential energy gained = 120 J

Explanation:

We're given the weight of the stone that is 4 N.

and weight of a substance = its mass × g

• mg = 4

Secondly, the potential energy is gained when moving a particle along a height. So here the distance that'd matter is 30m.

Potential energy gained = mg × height

= 4 × 30

= 120 N
