Question

Two small identical conducting spheres are placed with their centers 0.53 m apart. One is given a charge of 12 times 10^-9 C, the other a charge of -16 times 10^-9 C. (a) Find the electrostatic force exerted on one sphere by the other. magnitude N direction (b) The spheres are connected by a conducting wire. Find the electrostatic force between the two after equilibrium is reached, where both spheres have the same charge. magnitude N direction Calculate the magnitude and direction of the Coulomb force on each of the three charges shown in the figure below. 6.00 mu C charge magnitude 6.00 mu charge direction 1.50 mu C charge magnitude

Answer 1

(1) ans

Given that

charge q1=12*10^-9 C

charge q2=-16*10^-9 C

distance d=0.53 m

now we find the electric forces

the electric force F=kq1q2/d^2=9*10^9*12*-16*10^-18/0.53^2=-6.2*10^-6 N

the electric force is repulsive

now we find the electric force having same charges (q=12*10^-9 C

electric force F=9*10^9*12*12*10^-18/0.53^2=4.6*10^-9 N

the direction of the force attractive
