In UCM, the radius vector has

Find the electric field strength vector if the potentail of this field has the form varphi = ar , where is a constatn vector, and r is the radius vector of point of the field.

For one complete revolution, the angle swept by the radius vector is :

The angle between the radius vector and the centripetal force is

In non-uniform circular motion, the resultant acceleration makes an angle with the radius vector is

The curves for which the length of the normal is equal to the length of the radius vector is/are

Angular displacement is the_____through which the radius vector rotates.

Angle between radius vector and centripetal acceleration is

Angle between radius vector and centripetal acceleration is
