Q.
Consider the mechanical vibrating systems shown in figure $A,\ B,\ C\ and\ D$. The vibrations are simple harmonic in
A) $A,\ C$
B) $A,\ B,\ C$
C) $B,\ D$
D) $A,\ B,\ C,\ D$
Explanation
(b) The motion of a load attached to a spring, when pulled and released, is a SHM. The motion of liquid contained in U-tube when it is compressed once in one limb and left to itself and the twisting motion in figure $B$ are also simple harmonic.
