Question

Please answer parts A,B,&C. Thank you!

p06 infinity.) Part C

Answer 1

Given is:-

The potential  

and electric field  

Now,

part-a

We know that the electric field for any charge is given by

by plugging all the values we get

which gives us

Part-b

The potential due to the charge is given by

by plugging all the values we get

which gives us

Part-c

As,the electric potential at the given point is positive, then the given charge is positive.

Hence,

The direction of electric field is    from the given positive point charge
