A simple pendulum is constructed from a short metal rod of the mass mand of the length / suspended horizontally to the ground by the middle on a weightless wire of length L. The rod is carrying current / in the direction towards the viewer as shown in the picture below. The magnetic field Bis turned on perpendicular to the rod in the direction as shown in the picture below. Write down an expression for the force on the rod due to magnetic field along (tangentially to) the arc of motion of the simple pendulum. Please use "*" (without the quotes) for products (e.g. B*A), "/" for ratios (e.g. B/A) and the usual "+" and "-" signs as appropriate. For exponents (e.g. A2) use A*A or A^2 notation: thus A³/B should appear as either A*A*A/B or A^3/B. For greek letters use "theta" (without the quotes) and for trigonometric functions use "cos", "tan", "sin" (without the quotes). Thus for Acoso use A*cos theta.
