To study the net effect of two or more forces acting on a body in different directions, we can perform an experiment using a simple setup involving a spring balance, weights, and a pulley system. This experiment allows us to visually observe and measure the net effect of forces acting on a body.

**Materials Needed:**
- Spring balance
- Weights of different masses
- Pulley system (with string and a small pulley)
- Clamp stand or any support structure
- Stopwatch or timer

**Procedure:**
1. Set up the pulley system by attaching a small pulley to a clamp stand or any support structure. Attach a string to the pulley.
2. Hang the spring balance from the string attached to the pulley and secure it in place.
3. Place a weight on one side of the spring balance and note down the reading on the spring balance.
4. Add another weight of a different mass to the opposite side of the spring balance and note down the reading again.
5. Measure the time it takes for the weights to reach the ground when released from rest.
6. Repeat the experiment with different combinations of weights and masses.

**Observations:**
- The spring balance readings will provide us with the magnitude of the forces acting on the body.
- The time taken for the weights to reach the ground will allow us to compare the net effect of the forces.

**Analysis:**
By comparing the readings on the spring balance and the time taken for the weights to reach the ground, we can determine the net effect of the forces acting on the body. If the weights on both sides of the spring balance are equal, the net effect will be zero, and the body will remain stationary. However, if the weights on one side are greater than the other, the body will experience a net force in the direction of the greater weight, causing it to move in that direction.

**Conclusion:**
Through this experiment, we can understand how different magnitudes and directions of forces acting on a body result in a net effect. By measuring the spring balance readings and the time taken for the weights to reach the ground, we can quantitatively analyze the net effect of forces and observe their impact on the motion of the body. This experiment helps in understanding the principles of forces and their effects on objects in different directions.
