A 7.03-/C charge is located 1.66 m from a 4.58-nC point charge (a) Find the magnitude of the electrostatic force that one charge exerts on the other. (b) 1s the force attractive or repulsive? repulsive Asmul sphere of mass m “ 6.90 g and charge e.-31.2 nC is attached to the end or a mng and hangs vertealy as charge e2 "-58.0 rC is located below te frt darge·distance _ 2.000, below me nnt dange as the fore. te nee A second charge or equi, sus and (a) Find the tension in the string tb) it the string can withstand a maxmun tension of 0 580 N, what is the smaliest vae the string breks a0 controloption

Explanation / Answer

1-

a) Given q1 =7.03 nC =7.03 ×10^-9 C

q2=4.58 ×10^-9 C

d =1.66 m

Also constant k =9×10^9

So using Coloumb law

F = k× q1 ×q2 / d^2

F =9×10^9 × 7.03 ×10^-9 × 4.58×10^-9/ 1.66^2

F= 105.159 × 10^-9 N

b)

Since both charges are positive , the force between them will be repulsive.
