A) \[J\]
B) \[J-k{{g}^{-1}}\]
C) \[J-kg\]
D) \[J-k{{g}^{2}}\]
Correct Answer: B
Solution :
Gravitational potential \[\text{=}\frac{\text{work}}{\text{mass}}\] Hence, SI unit of gravitational potential \[\text{=}\frac{\text{unit}\,\text{of}\,\text{work}}{\text{unit}\,\text{of}\,\text{mass}}\] \[=\frac{J}{kg}=J-k{{g}^{-1}}\]
