Question

10. In deep space, two spheres of negligible size are connected by a 200-meter nonconducting cord. If a uniformly distributed charge of 0.04 C resides on the surface of each sphere, calculate the tension in the cord. a. 1,800 newtons b. 9,600 newtons c. 18,000 newtons d. 4,500 newtons e. 0 newtons

Answer 1

359.2 N

Step-by-step explanation:

The tension in the cord is due to the repulsive electrostatic force between the charged spheres connected by the cord.

`T=k(Q^2)/(d^2)`

k is the Coulomb constant = 8.98×10⁹ Nm²/C²

Q= 0.04 C

d = 200 m

`T=8.98*10^9((0.04)^2)/((200)^2) =359.2 N`
