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
- Av=~{{\left( \frac{3GM}{5R} \right)}^{1/2}}
- Bv=~{{\left( \frac{3GM}{4R} \right)}^{1/2}}
- Cv=~{{\left( \frac{4GM}{3R} \right)}^{1/2}}
- Dv=~{{\left( \frac{5GM}{4R} \right)}^{1/2}}
Correct answer
A. v=~{{\left( \frac{3GM}{5R} \right)}^{1/2}}
Step-by-step solution
Correct Option is : (A)
$v=~{{\left( \frac{3GM}{5R} \right)}^{1/2}}
$v=~{{\left( \frac{3GM}{5R} \right)}^{1/2}}
