1.	A cricket fielder can throw the cricket ball with a speed v_(0).If the throws the ball while running with speed u at an angle theta to the horizontal. The theta_(max) for which maximum range change if u lt lt v_(0) is
Answer» `pi/2` 0 `pi/3` `pi/4` Solution :If `U LT lt v_(0),theta_(max)=cos^(-1)[1/sqrt2]=pi/4`
