An electric dipole consists of two point charges, Q1 = +12 nC and q2 = -12 nC, placed 10 cm apart, see Figure.
(a) Compute the potential at points "a".
(b) Compute the potential energy associated with a point charge of +4.0 nC if it is placed
at points "b"
(c) Compute the potential energy associated with a point charge of +4.0 nC if it is placed
at points "C".
et = 1.6 x 10-19
K=9x 10° N. m²/C2

Aperson stands on a platform, initially at rest, that can rotate freely without friction. the moment of inertia of the person plus the platform is ip. the person holds a spinning bicycle wheel with its axis horizontal. the wheel has moment of inertia iw and angular velocity ωw. take the ωw direction counterclockwise when viewed from above. part a what will be the angular velocity ωp of the platform if the person moves the axis of the wheel so that it points vertically upward?
