If the units of force, energy and time are 20N, 100 J and 10s, find the units of mass and length.

Explanation

To solve the problem, we need to find the units of mass and length given the units of force, energy, and time.

### Step-by-Step Solution:

1. **Identify the dimensions of force, energy, and time**:
- The dimension of force (F) is given by the formula:
\[
F = m \cdot a
