The electrostatic force between two charges q1 and q2 is given by
where
is the Coulomb's constant and r is the distance between the two charges.
If we use F=19.2 N and q1=q2=-3.0 C, we can find the value of r, the distance between the two charges by re-arranging the previous formula:

Answer:
Mass of receiver is 92 kg
Explanation:
We have given mass of tackler
Let the mass of receiver is
When tackler moving alone velocity is m/sec
And when tackler and receiver is together velocity is = 2.5 m/sec
So from conservation of momentum
So mass of receiver is 92 kg
