Question

In activity to study variation in range of jet of water with change in the angle of projection.
What we have to write in the observation table?
Like, angle of projection of jet of water at 15° = range of project,?, OB1

Answer 1

Set the water tap such that the distance is few metres. Ask your laboratory bearer to make a mark B1 on the slab where the jet falls. Change the angle to 30°, 45°, 60° and 75° and repeat step 8 to get marks B2, B3, B4 and B5. ... These distances give range R for different angles (and same velocity).
