The magnitude of the centripetal acceleration is:
Av squared times R
BR squared times v
Cv squared over R
DR squared over v
Answer & Solution
Correct answer: C. v squared over R
1. It depends on the speed and the radius.
2. The magnitude is v squared divided by R.
3. It is always directed towards the centre.
