Question

# A vertical jet of water coming out of a nozzle with velocity 20 m/s supports a plate of mass M stationary at a height h = 15m, as shown in the figure. If the rate of water flow is 1 litre per second, the mass of the plate is (Assume the collision to be inelastic).

- 1 kg
- 1.414 kg
- 2 kg
- 10 kg

## The correct answer is: 1 kg
