Question

a load having mass of 800 grams is raised from a height of 2m to 10m slowly. calculate increase the potential energy of the Load.​

Answer 1

Explanation:

Potential energy at 2m

P.E = mgh

= 800× 10^-3 × 10×2

= 16

P.E at 10m

P.E = mgh

= 800×10^-3 × 10 × 10

= 80

So increase = 80-16 = 64
