If the speed (v) of the bob in a simple pendulum is plotted against the tangential acceleration (a) , the correct graph will be represented by -

Step-by-step solution

In SHM a =- ² x array l v = A ²- x ² v ²= ² ( ~A ²- x ² ) v ²= ² ~A ²- ² a ² ² v ²+ a ² ² = ² ~A ² v ² ² ~A ² + a ² ⁴ ~A ² =1 array i.e. ellipse
