Question

You place a neutral block of nickel near a small glass sphere that has a charge of 7 x 10-8 C uniformly distributed over its surface, as shown in the figure below. Px Charged sphere Neutral nickel block (a) About how long do you have to wait to make sure that the mobile electron sea inside the nickel block has reached equilibrium? e) about 1 s several hours @ less than a nanosecond (1 x10-9 s) O about 10 min (b) In equilibrium, what is the average drift speed of the mobile electrons inside the nickel block? 0 m/s about 1 × 10-5 m/s about 1 105 m/s

Explanation / Answer

(a)Less than a nanosecond (1 x 10^-9 s)

This occurs very fast that you cant even imagine so the time will be of the order of nano seconds.

(b)0 m/s

In equilibrium satate, no movement of electrons inside the metal.

(c)The mobility of an electron inside the metal, in (m/s)/(N/C)
