NEET Physics Question - Work Energy and Power - Potential Energy & Equilibrium

Rankers Physics

Topic: Work Energy and Power

Subtopic: Potential Energy & Equilibrium

A man pulls a bucket full of water from h metre deep well. If the mass of rope is m and mass of bucket full of water is M, then work done by the man is

( m + M/2) gh

( m + M) gh

( m/2 + M) gh

( 2m + M) gh

Solution:

Bucket of mass M will rise by a distance of h.

While center of mass of the rope rises by height of h/2.

So, Work Done = (M+m/2).g.h

Solution:
