Question

please help with the last part, please explain.

Two charges q1 and q2 have a total charge of 11.5 C When they are separated by 4.1 m, the force exerted by one charge on the other has a magnitude of 8 m Find 91 and q2 if both are positive so that they repel each other, and qi is the smaller of the two. For the universal constant k use the value 8.99 × 109 N m qi = 1.494 1494 OK That is correct! You are setting up and solving the quadratic equation to get to this answer 2 attempt(s) made (maximum allowed for credit = 5) [after that, multiply credit by 0.5 up to 10 attempts] 92 = 10.006 10.006 OK AC That is correct! It is very easy to get this value from your answer to the previous question Find qi and g2 if qi is positive and the other is negative so that they attract each other q1 =

Explanation / Answer

q1-q2 = 11.5 uC......(1)

F = k*q1*q2/d^2

8*10^-3 = -8.99*10^9*q1*q2/(4.1^2)....(2)

solving (1) and (2) we get

q1 = 1.5*10^-6 C = 1.5 micro C

q2 = -10*10^-6 C = -10 micro C
