JEE Main Physics question
A body moving in a circular path with constant speed reverses its sense of revolution (i.e., starts traversing the circle in the opposite sense) while its speed remains unchanged. Which of the following is then true about the centripetal force on the body?
Answer: (A)
Solution
The centripetal force has magnitude , which depends only on the speed (unchanged) and radius (unchanged), and always points toward the
