An Intiative by Sri Chaitanya

When the string makes an angle $90^{\circ}$ with the vertical, the tangential acceleration is zero & radial acceleration is somewhere between maximum and minimum

When the string makes an angle $90^{\circ}$ with the vertical, the magnitude of tangential acceleration is maximum & radial acceleration is somewhere between maximum and minimum

At no place in the circular motion, tangential acceleration is equal to radial acceleration

Throughout the path whenever radial acceleration has its extreme value, the tangential acceleration is zero.
