A dipole is composed of a pair of point charges ±, separated by a distance and aligned parallel with the - axis, as shown in the figure. Find the expression for the potential on the - axis at point F located at =8.70×10−8 cm, where ≫. Then, evaluate the potential for a dipole moment of =6.21×10−30 C·m. The Coulomb force constant is =1/(40)=8.99×109 N·m2/C2.

Acoil formed by wrapping 80 turns of wire in the shape of a square is positioned in a magnetic field so that the normal to the plane of the coil makes an angle of 28.0° with the direction of the field. when the magnetic field is increased uniformly from 200 µt to 600 µt in 0.400 as, an emf of magnitude 80.0 mv is induced in the coil. what is the total length of the wire?

What object a collides with object b and bounces back its final momentum is?
