Answer:
The magnitude of the electric field strength = 7.2 x 10⁸ N/C
Explanation:
The linear density:

Point r = 3 cm = 3/100 m
r = 0.03 m
The electric field strength is calculated below

The magnitude of the electric field strength = 7.2 x 10⁸ N/C
Answer:yes because of increase of intermolecular space
Due to increase in heat
