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:

CONCEPT:

Gravitational field intensity - The strength of the gravitational field is known as the gravitation field intensity and it is equal to the ratio of force to the mass of the body. It is written as;

I_g = \(\frac{F}{m}\)

Here, F is the gravitational force, and m is the mass of the given body.

CALCULATION:

Given : Mass of the body, m = 60 g = 0.06 kg

Gravitational force, F = 3.0 N

The gravitational field intensity is written as;

Ig = \(\frac{F}{m}\) ----(1)

Now, On putting all the given values in equation (1) we have;

Ig = \(\frac{3.0}{0.06}\) 

⇒ I_g = 50 N/kg

Hence, option (3) is the correct answer.
