Answer:
E = electric field
Step-by-step explanation:
The electric force per unit charge is called electric field of an object. It can be also defined as the space surrounded by a charged particle. The mathematical definition of electric field is given by :
![Electric field=(electric\ force)/(charge)](https://img.qammunity.org/2020/formulas/physics/high-school/bdnpieybxq7gavaegvc822dt0w5u0poaxc.png)
Where
Electric force = F
Charge = q
Electric field = E
So, electric field is represented by a symbol E. Hence, the correct option is (b).
