Problem o02 An isolated conducting sphere has a 7.9 om radius. One wire cames a current of 1 into it while another wire aurrent or it. How long seconds would it take for the sphere to in potential by 1300 Number is +/-2% Question Attempts: o of 5 used

Explanation / Answer

The potential on the sphere is

V = kq/r

change in potenetial is

del V = k del q/r

del q = r del V/k

del i = i_in - i_out= del q/ del t

del t= del q/ i_in- i_out

= r del V/ k ( i_in- i_out)

=0.079(1300 V)/ 9 * 10^9 ( 1.0000048-1.0000000)

=2.37 * 10^-3 s (or)

=2.37 ms
