A) 1.59 cm
B) 2.38 cm
C) 0.79 cm
D) 1.38 cm
Correct Answer: C
Solution :
[c] \[x={{m}_{{}^{g}/{}_{K}}}=G{{M}_{{}^{m}/{}_{{{R}^{2}}}}} k\Rightarrow x\propto \frac{1}{{{R}^{2}}}\Rightarrow {{x}_{2}}\] \[={{\left( \frac{6400}{7200} \right)}^{2}}{{x}_{1}}=0.79cm\]You need to login to perform this action.
