The Gravitati...

Question

The Gravitational Force On a Body Of Mass $1.5 k g$ Situated at a Point Is $45 N$ .The Gravitational Field Intensity At That Point Is.

Open in App

Solution

Formula,

$F = \frac{G_{m} M}{r^{2}}$

$\frac{G_{m}}{r^{2}} = \frac{F}{M}$

$\Rightarrow I = \frac{F}{M}$ gravitational field intensity

$= \frac{45}{1.5} = 30$
