Question
The figure below shows fields E1, E2, E3, and E4 at point P, produced respectively by charges q1, q2, q3, and q4. What is the sign of each charge? (Select all that apply. ) (q3 is positive, and q4 is negative. (q3 is negative, and q4 is positive. q1 is negative, and q2 is negative. q1 is negative, and q2 is positive. For each network shown below, find the equivalent resistance between a and b. (Take R1 = 3. 4 Ohm. ) (Take R2 = 21. 2 Ohm. ) For each network shown below, find the equivalent resistance between a and b. (Take R1 = 3. 4 Ohm. ) (Take R2 = 21. 2 Ohm. )Explanation / Answer
q3 is negative and q4 is positive.
q1 is negative and q2 is positive.
a)1/Req=1/3.4+1/6+1/1
Req=0.6846
b)Req=10/2+21.2=26.2
