A) 200 gm wt
B) 400gmwt
C) 50 gm wt
D) 300 gm wt
Correct Answer: B
Solution :
We know that \[g=\frac{GM}{{{R}^{2}}}\] On the planet \[{{g}_{p}}=\frac{GM/7}{{{R}^{2}}/4}=\frac{4g}{7}=\frac{4}{7}g\] Hence weight on the planet \[= 700 \times \frac{4}{7}\,=\,\,400 gm wt\]You need to login to perform this action.
