The electric dipole moment of a dipole in a 300 n/c electric field is initially perpendicular to the field, but it rotates so it is in the same direction as the field. if the electric dipole moment has magnitude 2.0 x 10- cm, what is the work done by the field? a) w12 x 10-7j b) w-6.0 x 10-7j c) w +6.0 x10-? j d) w +12 x 10-7 j =

Aspring with a mass of 2 kg has a damping constant 14 kg/s. a force of 3.6 n is required to keep the spring stretched 0.3 m beyond its natural length. the spring is stretched 0.6 m beyond its natural length and then released. find the position of the mass at any time t. (assume that movement to the right is the positive x-direction and the spring is attached to a wall at the left end.)

Avery long solenoid of inner radius 2.75 cm creates an oscillating magnetic field of the form = for this solenoid, =0.00425 t and =319 rad/s. (a)what is the maximum value of the induced electric field at a perpendicular distance 1.45 cm from the axis of the solenoid? (b) what is the maximum value of the inducted electric field at a point 5.85 cm perpendicular from the axis of the solenoid?
