Question

In the frame of reference of a rotating turntable, an insect of mass m is moving radially outwards (+ x direction) with a speed v. If the turntable is rotating with a constant angular velocity ωk in the vertically upward direction, the net pseudo force on the insect, when it is at a distance from the axis of the turntable is given by 

(1) imω² r + 2 jmωv 

(2) imω² r − 2 jmωv 

(3) − imω² r + 2 jmωv 

(4) imω² r

Answer 1

The Correct option is (4) imω² r
