Two point-charges of +1uC and -luc are kept at a distance of 2 cm. They form an electric dipole.
This dipole is situated in a uniform electric field of
1 x 105N-C-1, with dipole moment vector p making
an angle of 30° with the field. Calculate (i) the
magnitude of electric dipole moment and (ii) the
torque acting on the dipole. (iii) When would be the
torque maximum? How much?

Suppose that a mass of 2 kg is attached a spring whose spring constant is 50. the system is damped such that b = 12 . the mass is set in motion with an initial velocity of -8 m/s at a position 0 meters from equilibrium. set up and solve a differential equation that models this motion. write your solution in the form a cos ( ω t − α ) where α is a positive number. use your solution to fill in the information below: what is the amplitude of the motion? what is the value of ω ? what is the phase shift?
