MHT CET 2024 Physics question
The displacement of a particle performing S.H.M. is given by . If at t = 0, the displacement is y = 2 cm and velocity is , the value of amplitude A in cm is
Answer: (C)
Solution
The angular frequency is rad/s. Write the phase at as . Displacement: . Velocity: , so at its magnitude is , i.e. . Squaring and adding:
