A body weights 98 N on a spring balance at the north pole. What will be its weight recorded on the same scale if it is shifted to te equator? Use g=`GM/R^2=9.8m/s^2` and the radius of the earth R=6400 km.

Explanation

To solve the problem of finding the weight of a body at the equator compared to its weight at the north pole, we can follow these steps:

### Step 1: Understand the Weight at the North Pole
At the north pole, the weight of the body is given as 98 N. This weight can be expressed using the formula:
\[ W = mg \]
where:
- \( W \) is the weight,
- \( m \) is the mass of the body,
