Question
The weight of the body at a certain place is 30 N. The acceleration due to gravity at that point is 10 m/s2. Find out the weight of the object at the place where the acceleration due to gravity is 5 m/s2?
- 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.
