Apoint charge 2 pc is concentric with two spherical conducting thick shells. the smaller spherical conducting shell has a net charge of −27 pc , radii 2.6 cm and 4.7 cm , inner surface charge q ′ 2 and outer surface charge q ′′ 2 . the larger spherical conducting shell has a net charge of 14 pc , radii 6.1 cm and 7.4 cm , inner surface charge q ′ 3 and outer surface charge q ′′ 3 . what is the charge on the inner surface of the smaller spherical conducting shell, 2.6 cm from the 2 pc point charge? under static conditions, the charge on a conductor resides on the surface of the conductor. answer in units of pc.

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
