Write down an expression for the net force along the (tangentially to) arc of motion on a simple pendulum made of a metal rod of the length l and the mass m carrying  the current I . The rod is suspended by the middle on a weightless wire of the length L in the magnetic field B  and the gravitational field g perpendicular to the rod (see picture below).

Write down an expression for the net force along the (tangentially to) arc of motion on a simple pendulum made of a metal rod of the length / and the mass m carrying the current /. The rod is suspended by the middle on a weightless wire of the length L in the magnetic field B and the gravitational field g perpendicular to the rod (see picture below). 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.
