Question

A particle of mass 20 g experiences a gravitational force of 4.0 N along positive x - direction. Find the gravitational field at that point.

Answer 1

Given:-

Mass of the particle m = 20g.

Gravitational Force F = 4.0N.

To Find:-

Gravitational Field.

Solution:-

As we know that the force F = Em, ...........(1)

where E is the gravitational Field.

then putting the given values in equation (1), we get

F = Em

4î = E x 20x10⁻3kg

E = $\frac{4}{20x10^{-3} }$

E = $\frac{4x10^{3} }{20}$

Solving above equation we get

E = 200î N/Kg, Gravitational Field
