wo positively charged particles fixed in place on an x axis.
The charge are q1=1.60*10^19 C and q2=3.2*10^
9 C.
The particles are separated by R=0.0200m.
What are the magnitude and direction of the electrostatic
orce F12 on particle 1 from particle 2.
irst let's build a diagram.
This is a one
imensional problem with everything
ccuring on the xaxis.
Please excuse my
ack of artistic ability.
ow recall that the Coulomb force between two charges (q and
) is given by the following equation.
Also remember the sign
onvention.
..
like charges ("positive" force) repel and opposite
harges ("negative" force) attract.
ow input our variables and solve.
s we said earlier, a positive result means the charges are alike and therefore that the force is repulsive.
So we say that
harge 1 moves away from charge 2, or that charge 1 moves to the left.
The magnitude is 1.15 * 10^52 N
