Two charges of # 2# # C # and # 4# #C# are positioned on a line at points # -5 # and # -2 #, respectively. What is the net force on a charge of # 3 # #C# at # 1 #?
1 Answer
The forces on the
The net force is
Explanation:
The charges in question are all positive, so the forces will be repulsive. The
The distance from the
The net force, then, is:
where
This is a very large force, but these are very large charges, quite close together, and the constant is large.
