C) If assertion is true but reason is false.
D) If the assertion and reason both are false.
E) If assertion is false but reason is true.
Correct Answer: A
Solution :
According to Newton?s law of gravitation, \[F=\frac{G{{m}_{1}}{{m}_{2}}}{{{r}^{2}}}\]. When \[{{m}_{1}},\,{{m}_{2}}\] and \[{{r}_{2}}\] all are doubled, \[F=\frac{G(2{{m}_{1}})(2{{m}_{2}})}{{{(2r)}^{2}}}=\frac{G{{m}_{1}}{{m}_{2}}}{{{r}^{2}}}\], i.e. F remains the same.
