1.	A mass.m. is released, with a horizontal speed v from the top of a smooth and fixed, hemispherical bowl, of radius r. The angle theta w.r.t. the vertical where it leaves contact with the bowl is
Answer» `SIN^(-1)(v^(2)/(3rg) + 2/3)` `cos^(-1)(v^(2)/(3rg) + 2/3)` `tan^(-1)(v^(2)/(3rg) + 2/3)` `cos^(-1)(2/3)` ANSWER :B
