U(r)=A/(r^(2))-B/r, where is the distance from the centre of the force and A and B are positive constants.

U(r)=A/(r^(2))-B/r, where is the distance from the centre of the force

1.	U(r)=A/(r^(2))-B/r, where is the distance from the centre of the force and A and B are positive constants.
Answer» The equilibrium distance is GIVEN by2A/B The WORK required move the PARTICLE from equilibrum distance to infinity is `(B^(2))/(4A)` The work required move the particle from equilibrium distance to infinity is `B/(4A)` Only a Answer :A::B
