Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The escape velocities of planet A and B are same. But A and B are of unequal mass.
Reason R : The product of their mass and radius must be same. M1R1 = M2R2
In the light of the above statements, choose the most appropriate answer from the options given below :
Solution
${v_e}$ = escape velocity<br><br>${v_e} = \sqrt {{{2GM} \over R}}$<br><br>so for same ${v_e},{{{M_1}} \over {{R_1}}} = {{{M_2}} \over {{R_2}}}$<br><br>A is true but R is false
