Simple but not so simple #pyqJEE SHM

A particle performs simple harmonic motion with amplitude A. Its speed is trebled at the instant that it is at a distance (2A)/3 from equilibrium position. The new amplitude of the motion is:
(a) A * sqrt(3) (b) (7A)/3

(c) A/3 * sqrt(41) (d) 3A

One of the most conceptual question I have ever seen....Ex 2 #source #process Electrostatic

Especially did not click circuit R1. See that if such a circuit is present, then check for wheatstone
