Expert Solution

Given that
           q = 1.2nC
              = 1.2*10^-9C
Distance(2L) between two charges = 2.4mm
                                                   = 2.4*10^-3m

a)

Now the formula for the electric field is

Where
                 q = 1.2*10^-9C
                2L = 2.4*10^-3m
                 d = 10cm = 0.1m
Substitute all these given values in the above mentioned formula weget the result.

b)
Now the point is on the axial line of the dipole.
So the formula for the electric field is

Where
               P = q(2L)
             q = 1.2*10^-9C
             2L = 2.4*10^-3m
d = 10cm =0.1m
Substitute all these given values in this formula
Do the calculation work.
