Answer: q2 = -0.05286
Explanation:
Given that 
Charge q1 = - 0.00325C
Electric force F = 48900N
The electric field strength experienced by the charge will be force per unit charge. That is 
E = F/q
Substitute F and q into the formula 
E = 48900/0.00325
E = 15046153.85 N/C
The value of the repelled second charge will be achieved by using the formula 
E = kq/d^2
Where the value of constant 
k = 8.99×10^9Nm^2/C^2
d = 5.62m
Substitutes E, d and k into the formula 
15046153.85 = 8.99×10^9q/5.62^2
15046153.85 = 284634186.5q
Make q the subject of formula 
q2 = 15046153.85/ 28463416.5
q2 = 0.05286
Since they repelled each other, q2 will be negative. Therefore, 
q2 = -0.05286
