Explanation:
Intensity is given by the expresion:
where:
Io = inicial intensity
r1= initial distance
r= final distance
Explanation:
(a) Formula to calculate the density is as follows.
=
=
Now, calculate the charge as follows.
=
= C
or, = 101.06 nC
(b) For r = 6.50 cm, the value of charge will be calculated as follows.
=
= 7.454

Answer:30 cm
Explanation:
Given
