Question:
Gravitational field is
Gravitational field is
Updated On: Jul 2, 2022
- conservative
- non-conservative
- electromagnetic
- magnetic
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
A gravitational field is conservative field and due to this energy is conserved. The result is that the sum of the potential and kinetic energies remains constant (Hence, the name conservative field).

Concepts Used:
Gravitation
In mechanics, the universal force of attraction acting between all matter is known as Gravity, also called gravitation, . It is the weakest known force in nature.
Newton’s Law of Gravitation
According to Newton’s law of gravitation, “Every particle in the universe attracts every other particle with a force whose magnitude is,
- F ∝ (M1M2) . . . . (1)
- (F ∝ 1/r2) . . . . (2)
On combining equations (1) and (2) we get,
F ∝ M1M2/r2
F = G × [M1M2]/r2 . . . . (7)
Or, f(r) = GM1M2/r2
The dimension formula of G is [M-1L3T-2].
