1.5 Kg mass placed at a certain point experience a gravitational force of 45 N. Then the intensity of the gravitational field at that point is

Options

A. `67.5 N kg ^(-1)`
B. `45 N kg ^(-1)`
C. `30 N kg ^(-1)`
D. `15 N kg ^(-1)`

Answer

C

Explanation

`F = mI `
`therefore I = (F)/(m ) = (45)/(1.5) = 30 N kg ^(-1)`
