Question

Points A and C represents different positions on the

surface of the earth. Point B represents the centre of the earth.

Q) At which point on the surface of earth does a body experience maximum weight?​

Answer 1

Given:

Points A and C represents different positions on the surface of the earth. Point B represents the centre of the earth.

To find:

At which point does a body experience max weight?

Calculation:

So, we need to identify that point where the gravitational acceleration is maximum.

• "A" is in the poles.

• "B" is centre of earth.

• "C" is in equator.

Now, we know that in the equator, gravitational acceleration (g) is lesser than that of poles because of :

• Rotation of earth
• Distance of equator > Distance of poles from centre.

Also, gravitational acceleration (g) is zero at centre of earth (at point B).

Hence, max weight will be experienced at point A (or at poles) , because of max 'g' value.

Answer 2

Answer:

Now the weight of the body is directly proportional to the acceleration due to the gravity on the surface of the earth. So the weight of the body is maximum at the poles and minimum at the equator on the surface of the earth.
