Two point charges +q=1 μC and −q=−1 μC with mass m=1 g are fixed at the positions ±r⃗ 0 with |r0|=1 m. The charges are released from rest at t=0. Find the time τ in seconds at which they collide.Hint: Can you do it without integrating by using Kepler's laws?

Coulomb’s Law:
F=k•q₁•q₂/r² =…
F=ma => a=F/m=…
r=at²/2
t=sqrt{2r/a)=…

no not this way its accelaration is continuously increasing so integration is required......
