As shown in the figure below, a stick of length L = 0.435 m and mass m = 0.300 kg is in contact with a rough floor at one end and a frictionless bowling ball (diameter d = 15.00 cm) at some other point such that the angle between the stick and the floor is e = 30°.

Since we need to determine torques, before starting the problem, see if you can write an expression for the torque in terms of the force producing the torque and the perpendicular distance between the line of action of this force and the point about which we are determining the torques.
