Chapter 22: Q. 48 (page 626)

The net force on the1.0nCcharge in FIGUREP22.48is zero What isq?

Short Answer

Expert verified

Charge with net force is0.68nC.

Step by step solution

01

Figure for charge on net force

Figure is ,

02

Calculation for charge

Horizontal components are cancelled out by each other.

The vertical component's force is upward.

Because the web force onqis zero.

qmust be negative charged, causing to fall.

2Fcosθ=Fe

cosθ=213

2×14πϵo×(2)(1)13×213=14πϵo×(1)(q)(2)2

q=8×4133=0.68nc
