MHT CET 2022 Physics question
A particle of mass 'm' performs uniform circular motion of radius 'r' with linear speed 'V' under the application of force 'F'. If m, V and r are all increased by 50% the necessary change in force required to maintain the particle in uniform circular motion is
Answer: (A)
Solution
The centripetal force is . After a 50% increase of each quantity: , , . So . The change in force is $F' - F
