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 constant 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
