Q. If a beam of light passes through a prism with an angle of 60 degrees and the refractive index of the prism is √3, what is the angle of minimum deviation?

A. 30 degrees
B. 60 degrees
C. 45 degrees
D. 15 degrees

Solution

Using the formula for minimum deviation, D = (n - 1)A. Here, n = √3 and A = 60 degrees. Thus, D = (√3 - 1) * 60 degrees, which approximates to 30 degrees.

Correct Answer: A — 30 degrees

Q. If a block is on a horizontal surface and a force is applied at an angle, how does this affect the normal force acting on the block?

A. Increases normal force
B. Decreases normal force
C. No effect on normal force
D. Depends on the angle

Solution

Applying a force at an angle reduces the normal force because part of the applied force acts vertically upward, counteracting the weight of the block.

Correct Answer: B — Decreases normal force

Q. If a boat can travel 20 km upstream in 4 hours, what is the speed of the current if the speed of the boat in still water is 10 km/h?

A. 2 km/h
B. 3 km/h
C. 4 km/h
D. 5 km/h

Solution

Speed upstream = distance/time = 20/4 = 5 km/h. Speed of current = speed of boat - speed upstream = 10 - 5 = 5 km/h.

Correct Answer: A — 2 km/h

Q. If a boat can travel at 15 km/h in still water and the current is 5 km/h, what is the speed of the boat upstream?

A. 10 km/h
B. 15 km/h
C. 20 km/h
D. 25 km/h

Solution

Speed upstream = speed of boat - speed of current = 15 - 5 = 10 km/h.

Correct Answer: A — 10 km/h
