Answer 2

Explanation:

given,

Mass of boy = 50 kg

Number of stairs = 40

Height of each stair = 0.15 m

Total height covered by the boy

0.15 * 40 = 6m

since we know,

potential energy is equal to the work done by the body

50*10*6

P.E = m*g*h

where

m is the mass of body

g is the gravity

h is the height

Substituting the values,

P.E = 50*10*6

P.E = 3000 joules

bhai .. hope..this answer is correct...
