A4.0 µc point charge and a 3.0 µc point charge are a distance l apart. where should a third point charge be placed so that the electric force on that third charge is zero? (use the following as necessary: l.)

Q must be placed at 0.53 L

Explanation:

Given  data:

q_1 = 4.0 μC , q_2 = 3.0μC

Distance between charge is L

third charge q be placed at  distance x cm from q1

The force by charge q_1 due to q is

                 ----1

The force by charge q_2 due to q is

                  --2

we know that net electric force is equal to zero

F_1 = F_2

x = 0.53 L

Q must be placed at 0.53 L

the force required to move the cart is divided by three or 33.33 n.

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
