Question

Particle moves on the x-axis according to the equation x = A + B sin wt. The motion is simple harmonic with amplitude.

• A. A
• B. B
• C. A + B
• D. $\sqrt{A^{2} + B^{2}}$

Answer 1

Answer: (B)

B

Answer 2

Compare with

E = E₀ + a sin wt

When t = 0, x = A + sin 0 = A

So, A represents initial position.
