An insect trapped in a circular groove of radius 12 cm moves along the groove steadily and completes 7 revolutions in 100 s.
Is the acceleration vector a constant vector? What is its magnitude?

Text Solution

Verified by Experts

The acceleration is directed radially towards the centre of the circular groove. As the insect moves along the groove, its direction of acceleration changes but its magnitude remains constant.
Its magnitude is `(v^(2))/( r) = ((5.28)^(2))/(12) = 2.32 " cm"cdot s^(-2)`
