Question

If the acceleration due to gravity at any point is g/2, then the intensity of gravitational field at that point will be-
A) g/2. B) 2g
C) g D) zero​

Answer 1

Answer:

space around a body where the gravitational force exerted by it can be experienced by any other particle is known as the gravitational field of the body. The strength of this gravitational field is referred to as intensity, and it varies from point to point.

Consider the gravitational field of a particle of mass m located at the origin (O).

Suppose that a test particle of mass m0 is placed at the point P(x, y, z). The force of gravitational attraction exerted on the test particle is given by,

Answer 2

Answer:

The intensity of gravitational field at that point will be g/2.

Explanation:

• Gravitational field intensity is the force of gravitation per unit mass

                                          $\mathrm{I}=\frac{\mathrm{F}}{\mathrm{m}}=\frac{\mathrm{GMm}}{\frac{\mathrm{R}^{2}}{\mathrm{~m}}}=\frac{\mathrm{GM}}{\mathrm{R}^{2}}$

• The earth attracts (or pulls) all the objects towards its centre. The force with which the earth pulls the objects towards it is called the gravitational force of the earth or gravity.

                                                   $g=\frac{G M}{R^{2}}$

So, Acceleration due to gravity is same as the gravitational field intensity.

So if the gravity is g/2 .Then intensity of gravitational field is also g/2.
