NEET 2022, Physics Q27: Universal Law Of Gravitation And Field Intensity

NEET2022Physics

Q.

A body of mass 60 g experiences a gravitational force of 3.0 N, when placed at a particular point. The magnitude of the gravitational field intensity at that point is:

A
50 N/kg
B
20 N/kg
C
180 N/kg
D
0.05 N/kg

Solution

Gravitational field intensity $I_{g} = \frac{F}{m}$ .

$I_{g} = \frac{3.0}{60 \times 1 0 ^{- 3}} = 50$ N/kg.
