Answer:

Step-by-step explanation:
According to the gauss law
As we know that
Electric field is

where,
k = column constant =

q = charge
r = distance from the sphere center
For computing the magnitude of e first we have to need to find out the charge outside of sphere which is


q = -0.07 C
Now we have to find the electric field

The r is 2.5m but in question it is given 5m
So,
Electric field is
