Question

A) What is the magnitude of the positive charge? Answer in units of C.

B) What is the negative charge? Answer in units of C.

022 (part 1 of 2) 10.0 points Two conducting spheres have identical radii Initially they have charges of opposite sign and unequal magnitudes with the magnitude of the positive charge larger than the mag- nitude of the negative charge. They attract each other with a force of 0.183 N when sepa- rated by 0.5 m. equal magnitudes with the magnitude Initial The spheres are suddenly connected by a thin conducting wire, which is then removed Connected+ Now the spheres repel each other with a force of 0.03 N Fina+ What is the magnitude of the positive charge? Answer in units of C

Explanation / Answer

A ) since they repel by force 0.03 N

kq^2/r^2 = 0.03 N

r = 0.5 m

q = 0.9128 * 10 ^-6 C ( final charge )

force of attraction initially

k Q Q1/r^2 = 0.183

Q Q1 = 5.0833*10^-12

we know that

q = Q-Q1/2

Q-Q1 = 1.8256 *10 ^-6 C

from above equations we get

5.0833*10^-12/Q1 -Q1 =1.8256 *10 ^-6 C

solving we get

A) Q = positive charge = 0.000003345 C

B ) Q1 = negative charge = -0.00000151958 C
