QB2c. Write down an expression for the electromotive force (EMF) Ę in a metal disk of radius Rrotating in a magnetic field of strength B considering that the surface of the disk makes anangle a with the magnetic field. The disk is rotating with frequency f. Please use appropriatealgebraic symbols for multiplication (* for a × b), division (/ for a/b), exponents (a^b for a³),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" buttonto check you entered the answer you expect.EMF=
