A) \[\frac{G{{M}_{z}}}{D_{z}^{2}}\]
B) \[\frac{4G{{M}_{z}}}{D_{z}^{2}}\]
C) \[\frac{G{{M}_{z}}}{D_{z}^{2}}\]
D) None of these
Correct Answer: B
Solution :
Gravitation force on particle having mass m is,\[F=\frac{G{{M}_{z}}m}{{{({{D}_{z}}/2)}^{2}}}\] Now, acceleration due to gravity experienced by particle is\[g=\frac{F}{m}=\frac{G{{M}_{z}}}{{{({{D}_{z}}/2)}^{2}}}=\frac{4G{{M}_{z}}}{D_{z}^{2}}\]You need to login to perform this action.
