A magnet is suspended in the magnetic meridian with an untwisted wire. The upper end of wire is rotated through 180∘ to deflect the magnet by 30∘ from magnetic meridian. When this magnet is replaced by another magnet, the upper end of wire is rotated through 270∘ to deflect the magnet 30∘ from magnetic meridian. The ratio of magnetic moment of magnets is

Two inclined planes `OA` and `OB` of inclinations `alpha` and `beta` equal to `30 degree` are as shown in the figure. A particle is projected at an angle of `90 degree` with plane `OA` from point `A` and it strikes the plane `OB` at point `B` normally. Then find the speed of projection `u` in m/s. (Given that `OA = OB = 20cm` and `g = 10m/s^(2)`)
