    17
    Given below are two statements: one is labelled as Assertion A and the other is labelled as reason RR. Assertion A: The escape velocities of planet A and B are same. But A and B are of unequal mass. Reason RR : The product of their mass and radius must be same. M1R1=M2R2M_{1}R_{1}=M_{2}R_{2} In the light of the above statements, choose the most appropriate answer from the options given below:
