Question
Electrical force per unit charge is known as the _______________________.
In a certain region of space, lines of constant positive electric potential get farther apart as one moves to the right. The force on a negative charge in this region will point to the ____________________.
Imagine four equal positive charges, q, placed on points of a circle of radius r at the 3, 6, 9, and 12 o'clock positions. Coulomb's constant is k. The magnitude of the electric field at the center of the circle is given by
4 kq/r.

zero.
A charge of 1 C is placed in an Electric Field. At the point where the charge is placed the electric force on the charge is 20 N, the at this point the Electric Field is E = 20 N/C.
True
False
When we place a positive charge in an Electric Field, the directions of the Electric Field (E) and the Electric Force on the charge (F) are the same.
True
False
We bring a positive Electric Charge of 1 C from an infinite away distance to a certain point where the Electric Potential is 5 Volt. The total amount of Work done in the process is 50 Joules.
True
False
A charge of 4 C is placed in an Electric Field. At the point where the charge is placed the electric force on the charge is 20 N, the at this point the Electric Field is E = 1 N/C.

Explanation / Answer
Electrical force per unit charge is known as the _______electric field________________.
Imagine 4 equal charges ....... Zero(because all electric field canceled by each other)
A charge of 1C is placed in an electric field...........true. ( E= F/q= 20/1= 20N/C)
When we place a positive charge.......true( F=QE, force will be in same direction as that of electric field)
we bring a positive electric charge.......false ( Workdone=QV= 1x5= 5J)
