relation between potential difference and electric field is given as

so here we know that
d = 3 cm



So now when plates are separated to 4 cm distance carefully
the potential difference between them will change but the electric field between them will remain constant
So at distance of 4 cm also the electric field will be E = 1000 N/C
It is due to the excess stress.
Explanation:
The somatic nervous system coordinates the voluntary control of movement in the body system.
The nervous system is made up of the central nervous system and peripheral nervous system.
The peripheral nervous system is made up of the nerves that branches into the body from the spinal cord.
- It consist of the somatic nervous system and the autonomous nervous system.
- The somatic nervous system controls the voluntary actions of movement in the body.
- It coordinates the reflex arc.
