STANDARD Physics Gravitational Field and Potential MCQ Question
Type: MCQ-numerical-Medium-Class 11
The gravitational field intensity at a point 10,000 km from the centre of the Earth is 4.8 N kg⁻¹. The gravitational potential at that point is
A
−4.8 × 10⁷ J kg⁻¹
B
−2.4 × 10⁷ J kg⁻¹
C
4.8 × 10⁶ J kg⁻¹
D
3.6 × 10⁶ J kg⁻¹
Correct Answer
Option A
Detailed Explanation
Gravitational potential, V = −GM/R. Given E = 4.8 N kg⁻¹, V = −ER = −4.8 × 10000 × 10³ = −4.8 × 10⁷ J kg⁻¹.
