Question

A satellite revolving around a planet has a time period T and orbital radius R the mass of the this planet is -

• A.
• B.
• C.
• D. $\frac { 4 \pi ^ { 2 } \mathrm { R } ^ { 3 } } { \mathrm { GT } ^ { 2 } }$

Answer 1

Answer: (D)

$\frac { 4 \pi ^ { 2 } \mathrm { R } ^ { 3 } } { \mathrm { GT } ^ { 2 } }$

Answer 2

T = 2p$\sqrt { \frac { \mathrm { R } ^ { 3 } } { \mathrm { GM } } }$Ž T² = 4p² $\frac { \mathrm { R } ^ { 3 } } { \mathrm { GM } }$ Ž M=
