CAPE Physics Unit 1 · 2004 · Paper 2 · Question 4(d)(i)

The same mass of 0.60 kg is now rotated at the end of another string at a constant speed, v, in a vertical circle of radius 1.20 m. The minimum tension in the string is 2.1 N.

State and explain where the tension in the string is MAXIMUM and MINIMUM.

The mark scheme is shown once you've answered.
