A body is travelling in a circle at a constant speed. It

A body is travelling in a circle at a constant speed. It

Options

  1. Ahas a constant velocity
  2. Bis not accelerated
  3. Chas an inward radial acceleration
  4. Dhas an outward radial acceleration

Correct answer

C. has an inward radial acceleration

Step-by-step solution

Body moves with constant speed it means that tangential acceleration aT=0  and conly\mathrm{a}_{\mathrm{T}}=0 \ \text{ and } \mathrm{conly} centripetal acceleration aC\mathrm{a}_{\mathrm{C}} exists whose direction is always towards the centre or inward (along the radius of the circle).
