Question

39.
A mass is performing vertical circular motion (see
figure). If The average velocity of the particle is
increased, then at which point maximum breaking
possibility of the string :-
(1) A
(2) B
D
(3) C
(4) D​

Answer 1

Answer:

the avrage veloxity of the particleis increased

Answer 2

Answer:
