Question

Luke has a mass of 50kg. Leia has a mass of 45kg. They (their centers) are separated by a distance of 10m.
If I use a magic machine to triple Luke's mass and double Leia's mass and then also double their distance apart, how does the force of gravity between them change?

Answer 1

Answer:

Given that,

Mass of boy, m=50kg

Potential energy at a height of 45 steps , P=mgh=50×10×45×0.15=3375J

Time taken to climb 45 steps , t=9secs

Power of boy =

t

P

=

9

3375

=37

Answer 2

Answer:

37 is the wright answer
