The Electric field is E=23400 V/m.
What is electric potential ?
The amount of labor required to convey a unit of electric charge from a reference point to a given place in an electric field is known as the electric potential (also known as the electric field potential, potential drop, or the electrostatic potential). More specifically, it is the energy per unit charge for a test charge that is negligibly disruptive to the field under discussion.
The electric field of a spherical conductor is given by:
Here 'E' is the electric field and 'Q' is the electric charge.
therefore putting the values we get,
E=23400 V/m

Answer:
option (d)
Explanation:
A concave mirror always forms a real and inverted image of an object except when the object placed between pole and focus of the mirror.
When the object is placed beyond the centre of curvature, it forms a image which is smaller than the object but it is real and inverted in nature.
