Per NCERT §3.10 (text + eqn 3.45), the relation between linear speed v, angular speed ω, and radius R in UCM is which?
Av = R / ω
Bv = R² ω
Cv = ω / R
Dv = R ω
Answer & Solution
Correct answer: D. v = R ω
NCERT eqn 3.45: v = Rω (arc length per unit time = radius × angular displacement per unit time).
