A) \[4G{{M}_{p}}/D_{p}^{2}\]
B) \[G{{M}_{p}}m/D_{p}^{2}\]
C) \[G{{M}_{p}}m/D_{p}^{2}\]
D) \[4G{{M}_{p}}m/D_{p}^{2}\]
Correct Answer: A
Solution :
Force, \[F=\frac{G{{M}_{e}}m}{{{R}^{2}}}\]Here, \[F=\frac{G{{M}_{p}}m}{{{({{D}_{p}}/2)}^{2}}}\] \[F=\frac{4G{{M}_{p}}m}{D_{p}^{2}}\] \[F=ma\] Acceleration due to gravity \[a=\frac{F}{m}=\frac{4G{{M}_{p}}}{D_{p}^{2}}\]You need to login to perform this action.
