    22:25 1) Answer is √3R Because it is an equilateral triangle of side 2R and when we take half of it as right angle triangle and apply Pythagoras theorem taking hypotenuse as 2R and base as R then we get the perpendicular i.e. r perpendicular as √3R. 31:02 2) Angle is 90° Because there are two types of accelerations i.e. tangential and centripetal and in uniform circular motion tangential acceleration is zero only centripetal acceleration acts and we know that centripetal acceleration is always directed towards centre and here it is perpendicular to the velocity. Thus, angle between velocity and net acceleration is 90°.
