Two spherical massive bodies of uniform density each of mass `M` and radius `R` are kept at a distance `4R` apart. Then the minimum speed `(v_(min))` required to project a particle from the surface of body A such that it will never return on the surface of same body is

Options

A. `v_(min)=sqrt((12GM)/(5R))`
B. `v_(min)=sqrt((2GM)/(3R))`
C. `v_(min)=sqrt((5GM)/(7R))`
D. `v_(min)=sqrt((2GM)/(R))`

Answer

B
