Question

Gravitational potential $ V $ versus distance $ r $ graph is represented in figure. The magnitude of gravitational field intensity is equal to:, $ 8 \mathrm{~N} / \mathrm{Kg} $, $ 4 \mathrm{~N} / \mathrm{Kg} $, $ 6 \mathrm{~N} / \mathrm{Kg} $, $ 2 \mathrm{~N} / \mathrm{Kg} $

MARKS App · Accepted Answer

The gravitational field intensity is given by the Gradient of Gravitational potential means the Gravitational potential change in per unit length, hence the Gravitational field intensity will be, E → = ∆ V ∆ r = 8 - 4 1 sin ⁡ 30 o = 8 N k g - 1 ; will be the correct answer.
