2 A disc placed on a frictionless horizontal plank is rotating with a constant angular velocity about its central vertical axis Now the plank is made to move with a constant acceleration a on a straight path If you assume initial location of the centre of disc as origin direction of motion of the plank in negative y axis of the coordinate system attached with the plank which of the following equations represent trajectory of instantaneous centre of rotation of the disc a If a wk then y x 2 2a x 2a 22 x 2a w x 2a b If a wk then y c If ck then y d If wk then y and x 0 and x 0 and x 0 and x 0
