Answer:

The exerting force by the person is 294 N.

(3) is correct option.

Explanation:

Given that,

Mass of crate = 30 kg

Normal force = 150 N

When a person is lifting a crate then the crate does not contact the floor

So, the normal force is zero.

We need to calculate the exerting force by the person

Using formula of force

$F = ma$

$F=30\times9.8$

$F=294\ N$

Hence, The exerting force by the person is 294 N.
