1.	When a mass is rotating in a plane about a fixed point , its angular momentum is directed along
Answer» a LINE perpendicular to the plane of rotation the line MAKING an angle of `45^(@)` to the plane of rotation the radius the tangent to the orbit Solution :Let x be the DISTANCE of centre O of equilateral triangle from each side . Total torque about O = 0 `implies F_(1) x + F_(2) x- F_(3) x = 0` or `F_(3) = F_(1) + F_(2)`
