The electrostatic force between the glass bead and the plastic bead is given by:
where
k is the Coulomb's constant
q1 is the charge of the glass bead
q2 is the charge of the plastic bead
r is the separation between the two beads
In this problem,
and
, and since we know the force,
, we can rearrange the equation to find q2, the charge of the plastic bead:
Resistance is current x potential difference. So therefor run wafff
The net force on the object is 5 N.
Explanation:
We can calculate the net force on the object by using Newton's second law of motion:
where
F is the net force on an object
m is the mass of the object
a is its acceleration
For the object in this problem, we have
m = 1 kg is its mass
is its acceleration
Substituting into the equation, we find the net force:
