Question

The inverse square law applies to:

Answer 1

Answer:

Intensity of sound

Gravitational Force

Intensity of light

Electric Force

Explanation:

As we know that inverse square law will depends on the square of the distance inversely

So for

Intensity of sound or intensity of Light for very small size source we can say intensity will be defined as power per unit area.

So we can say

$I = \frac{P}{4\pi r^2}$

Now similarly we know that gravitational force is given as

$F = \frac{Gm_1m_2}{r^2}$

also we know that electrostatic force is given as

$F = \frac{kq_1q_2}{r^2}$

so all above are following inverse square law

Answer 2

There are more correct choices on the list than incorrect ones.

The inverse square law applies to

-- the intensity of sound from a small source

-- the Gravitational Force

-- the Intensity of light from a small source

-- the Electric Force  from a point charge or a small charge.

It doesn't apply to the Magnetic Force.
