Well now, I don't know !
Let's figure it out.

The charge on one electron is 1.60 x 10⁻¹⁹ Coulomb .

To get 3,500 Coulombs of charge, you'd need to
go around and collect

             (3,500) / (1.60 x 10⁻¹⁹)  electrons.

That's  2.19 x 10²²  of the little fellas.

That's a big number.  But what's REALLY amazing is the
mass and weight of that many electrons:

             Mass:    1.989 x 10⁻⁵ gram

             Weight:  about  0.0000007 ounce  !

That's not one electron.  That's the whole  <span>2.19 x 10²²  uvvum
that it takes to hold 3,500 Coulombs of charge.</span>

21.8452851 * 10^21 e. Which is 21.845.285.100.000.000.000.000 electrons. A lot.

-- Use the formula  D=(1/2)·(g)·(t²)  to calculate how long
it takes the flower pot to fall to the ground.

1.5 m = (1/2) · (9.8 m/s²) · (t²)

t² = (1.5 m) / (4.9 m/s²)

t = 0.554 second

-- Use the formula Distance = (speed)·(time) to calculate
how far the pot traveled horizontally in that amount of time.

Distance = (8 m/s) · (0.554 sec)

Distance horizontally = 4.43 meters

BALANCED FORCES

When two forces acting on an object are equal in size but act in opposite directions, we say that they are balanced forces . a stationary object stays still. ... a moving object continues to move at the same speed and in the same direction.
