Answer:
Scandium with an ion charge of +3
Explanation:
Longitude- Horizontal (East West)
Latitude- Vertical (North South)
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:
<span>umm it gives 1/v + 1/20 = -1/10 and v = -20/3 cm. Magnification = |v/u|=1/3.</span>
