Q.23 A disc of radius R is rolling without slipping on a horizontal surface such that velocity of centre of mass v0 is The instantaneous speed of point p as shown is (1) square root of 3 divided by 2 spacev0   (2) square root of 3 v0   (3) 2 divided by square root of 3 v  (4)  v0/square root of 3  

Dear Student,

Velocity along P will be equal to 2νοcos30o
As we know that the 
point farthest from the point of contact moves with twice that speed, so

Velocity along P= 2
νοcos30o3 νo
