A stone tied to a string moves in a vertical circle of radius 1.6 m. The minimum speed it must have at the top to keep the string taut is (g = 10 m/s²):
Answer: A. 4 m/s
Why: At the top, mg = mv²/r, so v = √(gr) = √16 = 4 m/s.
A shell at rest explodes into two fragments with masses in the ratio 1 : 2. The ratio of their speeds is:
Answer: C. 2 : 1, the lighter fragment moving faster
Why: The total momentum stays zero, so m₁v₁ = m₂v₂.
A 4 kg block rests on a rough inclined plane of angle 30°. Taking g = 10 m/s², the force of friction on it is:
Answer: A. 20 N
Why: The block is at rest, so friction balances the component of weight down the plane: mg sin30° = 20 N.
A coin placed on a card resting on a glass is dropped into the glass when the card is flicked away quickly. This is due to:
Answer: A. the inertia of rest of the coin
Why: The coin tends to stay at rest and falls straight down into the glass.
In the same Atwood machine (3 kg and 2 kg, g = 10 m/s²), the tension in the string is:
Answer: C. 24 N
Why: For the 2 kg mass, T − 20 = 2 × 2, so T = 24 N.
Newton's third law states that for every action there is:
Answer: B. an equal and opposite reaction acting on a different body
Why: Newton's third law: action and reaction forces are equal in magnitude, opposite in direction, and act on two different bodies (never the same one).
For a car taking a turn on a banked road without relying on friction, the required banking angle depends on:
Answer: A. the speed of the car and the radius of the turn
Why: For frictionless banked turns, tanθ = v²/(rg), so the ideal banking angle depends on the speed v and the radius of curvature r.
The area under a force–time graph gives the:
Answer: D. impulse (change in momentum)
Why: Impulse = ∫F dt = Δp.
