Answer:

The charges repel with different forces

Explanation:

The charges repel with different magnitudes. This can be seen from the equation:

F = k\frac{q_{1}q_{2}  }{r^{2} }

where q₁ and q₂ are the charges of the particles

k is Coulomb constant = 8.99 × 10⁹ Nm^{2} C^{-2}

r distance between the charges

So the force will be F = 8.99 * 10^{9} \frac{10^{-6}*1^{-6}  }{(0.25^{2} )}

                                    = 143 840 N

This is a large force, which shows that the forces repel each other.

const2013 [10]

Answer:

=18 sec

Explanation:

240m=20m/s, find 360m

360×20÷240=30m/s

time=distance÷speed

240÷20=12sec

if 240=12sec,find 360

360×12÷240
