Q: With what minimum speed should m be projected from point C in presence of two fixed masses M each at A and B as shown in the figure such that mass m should escape the gravitational attraction of A and B?

(a) $\displaystyle \sqrt{\frac{2GM}{R}}$

(b) $\displaystyle \sqrt{\frac{2\sqrt2 GM}{R}}$

(c) $\displaystyle 2\sqrt{\frac{GM}{R}}$

(d) $\displaystyle 2\sqrt2 \sqrt{\frac{GM}{R}}$

Ans: (b)
