QB2c. Write down an expression for the electromotive force (EMF) E in a metal disk of radius R rotating in a magnetic field of strength B considering that the surface of the disk makes an angle a with the magnetic field. The disk is rotating with frequency f. Please use appropriate algebraic symbols for multiplication (* for a × b), division (/ for a/b), exponents (a^b for ab), square root (sqrt(a*b/c) for √√ax b/c) etc. For greek letters use their names e.g. "theta", "alpha", "pi" (without the quotes) and for trigonometric functions use "cos", "tan", "sin" (without the quotes). Thus for Acose use A*cos theta. Please use the "Display response" button to check you entered the answer you expect.
