Question
A particle of mass m (where m is the mass in gram) is released from point O with initial velocity zero. The work done by gravitational force on the particle, when it is taken from O to B, is
- 30 m, unit
- – 15 m, unit
- – 30 m, unit
- + 15 m, unit
The correct answer is: 30 m, unit

A, B, C are vertices of an equilateral triangle imagined in free space (no gravity). First a mass m is brought from infinity to point A and the work done in doing so is WA. Then keeping m fixed at A, another identical mass m is brought from infinity to point B. The work done is WB. The work done by the another identical mass m brought from infinity to C is WC keeping A and B fixed. Then
