Three identical point charges, each of mass m 0.100 kg, hang from three strings, as shown in the figure below. If the lengths of the left and right strings are each L 28.0 cm, and if the angle is 45.0°, determine the value of q. Need Help Read It Chat About It Reader My Notes Ask Your Teacher

Explanation / Answer

the horizontal tension is equal to weight of the string

Tcos = mg

T = mg/cos

the vertical tension equal to force acting on the charges

Tsin = kq^2/(Lsin)2 + kq*(2q)/(2Lsin)2

dividing bot equations

mgtan = 1.5kq2/(Lsin)2

q = Lsin [mgtan/(1.5k)]

= (0.28 m) sin 45[(0.1 kg)(9.8)tan45/(1.5(9.0 * 10 ^9)]

= 1.686*10-6 C
