1.	A golfer hits a golf ball into the air over level ground. The velocity of the ball at a height of 10.3 m is vecv=(8.6hati+7.2hatj)m//s, with hati horizontal and hatj upward. Find (a) the maximum height of the ball and (b) the total horizontal distance traveled by the ball. What are the ( c) magnitude and (d) angle (below the horizonatl) of the balls velocity just before it touches the ground?
Answer» Solution :(a) `~~13M`, (b) `~~28M` ( C) 18 m/s, (d) `-62^(@)` (which is equivalent to `298^(@)`)

A wire is bent to form a semicircle of the radius a. The wire rotates about its one end with angular velocity omega . Axis of rotation is perpendicular to the plane of the semicircle . In the space , a uniform magnetic field of induction B exists along the aixs of rotation as shown in the figure . Then -
A massless non conducting rod AB of length 2l is placed in uniform time varying magnetic field confined in a cylindrical region of radius (R gt l) as shown in the figure. The center of the rod coincides with the centre of the cylin- drical region. The rod can freely rotate in the plane of the Figure about an axis coinciding with the axis of the cylinder. Two particles, each of mass m and charge q are attached to the ends A and B of the rod. The time varying magnetic field in this cylindrical region is given by B = B_(0) [1-(t)/(2)] where B_(0) is a constant. The field is switched on at time t = 0. Consider B_(0) = 100T, l = 4 cm(q)/(m) = (4pi)/(100) C//kg. Calculate the time in which the rod will reach position CD shown in the figure for th first time. Will end A be at C or D at this instant ?
