Question

# The weight of the body at a certain place is 30 N. The acceleration due to gravity at that point is 10 m/s^{2}. Find out the weight of the object at the place where the acceleration due to gravity is 5 m/s^{2}_{?}

- 30 N
- 10 N
- 15 N
- 5 N

Hint:

### Use the relation weight= mass x gravity

## The correct answer is: 15 N

### The correct option is c)15 N.

Given :

weight of object= 30 N

Acceleration due to gravity = 10m/s2

Now, we know ,

weight = mass x gravity

30 = mass x 10

mass= 3 kg

Now we need to find the weight of the object when the acceleration due to gravity is 5 m/s2.

We know that the mass of the object remains same as it independent of gravity.

Now,

Weight = mass x gravity

= 3 x 5

weight = 15N.
