Expert Solution
Step 1
a) Given data
- The magnitude of the charge on the sphere is given as q = 5e.
- The distance of the point from the sphere is given as r = 0.3 cm.
- 1e = -1.6 x 10-19 C.
The expression for the electric potential is given as,
Here, k is the coulomb's constant.
On putting the values as,
Thus, the potential at a distance 0.260 cm away is -2.4 x 10-6 V.
