What is the expression for the minimum speed v of the projectile (mass m) when it is projected from the surface of the sphere of mass M directly towards the center of the second sphere (mass 4M) with a center-to-center separation of 6R?

Options

  1. Av=~ ( 3GM 5R ) ^ 1/2
  2. Bv=~ ( 3GM 4R ) ^ 1/2
  3. Cv=~ ( 4GM 3R ) ^ 1/2
  4. Dv=~ ( 5GM 4R ) ^ 1/2

Correct answer

A. v=~ ( 3GM 5R ) ^ 1/2

Step-by-step solution

Correct Option is : (A) v=~ ( 3GM 5R ) ^ 1/2
