Per NCERT §7.7 (eqn 7.25), the gravitational POTENTIAL (per unit mass) at distance r from a point mass M is which?
AV_pot = G M r
BV_pot = −G M / r
CV_pot = −G M / r²
DV_pot = +G M / r
Answer & Solution
Correct answer: B. V_pot = −G M / r
NCERT §7.7: gravitational potential = U/m = −GM/r. Scalar; convention V(∞) = 0.
