Answer 2

Given:

Gravitational field in a = Ē= (3i +4j) N/kg

Mass of object = 2kg

Position of object = 2m, 3m

To find:

The magnitude of the gravitational force acting on the object

Solution:

Gravitational Force = Mass X Gravitational Field

Since the given field,  Ē is constant and independent of the position

⇒ The position of the object is of no significance while calculating the force experienced by the object.

Force = 2 X ( 3i + 4 j)

= (6i + 8j )N

The magnitude of the force = $\sqrt{6^{2} + 8^{2} }$

= $\sqrt{36+64} \\\sqrt{100}$ = 10N

Hence, the magnitude of the gravitational force acting on the object is 10N.
