Solution
Correct Answer:
6.25 N/kg
- Potential vs Field: For spheres, ∣V∣=rGM and E=r2GM.
- Direct Relation: E=r∣V∣.
- Apply Data:
- ∣V∣=62.5×106 J/kg.
- r=107 m.
- Calculation:
- E=10762.5×106=6.25 N/kg.
- Note: Gravitational field intensity has units of acceleration (m/s2), which is also expressed as N/kg.
