Numerical problems Calculate
Velocity of a body of mass 100 g having a K.E. of 20 J.

Explanation

To solve the problem of calculating the velocity of a body with a mass of 100 g and a kinetic energy of 20 J, we will follow these steps:

### Step-by-Step Solution:

1. **Convert Mass from Grams to Kilograms:**
- The mass of the body is given as 100 grams. To use the formula for kinetic energy, we need to convert this into kilograms.
- \( \text{Mass} = 100 \, \text{g} = \frac{100}{1000} \, \text{kg} = 0.1 \, \text{kg} \)
