1. A point p is located 56 cm to the right away from a point charge of 6.7 x 10^-10 C. What is the direction and magnitude of the electric field at point p? 

	19.21 N/C
	23.7 N/C
	11.5 N/C
	13.8 N/C

2. A point charge of charge Q is located some distance d away from a location p. If nothing changes, but p is moved twice as far away, what will happen to the electric field at point p?
The electric field will be 1/2 of what it was
The electric field will be 1/3 of what it was
The electric field will be 1/4 of what it was
The electric field will be 1/5 of what it was


If an atom has 13 protons and is currently electrically neutral, what must happen to give the same atom a positive charge of +2e?
2 electrons must be removed
3 electrons must be added
1 proton must be removed
2 protons must be removed
