Marks: +1, -0

A solid sphere is rolling without slipping on a semi-circulartrack of radius 10m as shown in the figure. The radius of solidsphere is much smaller than the radius of semi-circular track. Atthe lowest point, it has a velocity 10m∕s. To what maximumangle θ from the vertical will the sphere travel before it comesback down? Neglect the rolling friction between the sphere andthe track. ( Take, g=10m∕s2)
