Gravitational PotentialMediumQuestion 30705

Question

Gravitational potential V at distance r from mass M is:
  1. A
    GM/r
  2. B
    −GM/r
    Correct
  3. C
    GM/r²
  4. D
    −GMr

Correct answer

−GM/r

Explanation

V = −GM/r. It is always negative (attractive field), and zero only at infinity. The negative sign reflects that work must be done against gravity to move mass to infinity.
