Two charges of # -5# # C # and # -3 # #C# are positioned on a line at points # -8 # and # 6 #, respectively. What is the net force on a charge of # 3# #C# at # -1 #?
1 Answer
This is a linear problem, so we can just add up the forces on the
Explanation:
The forces on particles with charges
Where
To calculate the force on the
Since the charges are of opposite signs, this is an attractive force, acting to the left (i.e. the negative direction on the number line).
To calculate the force due to the
This is also an attractive force, due to the opposite charges, but it is acting to the right.
