How many of each component are shown in the diagram

One battery, two resistors, two switches, three light bulbs

Explanation:

Each component is indicated with the following symbols:

- Battery: it is the one on the right, consisting of two longer lines and two shorter lines. It is the device that provides the electromotive force to the circuit

- Resistors: they are the devices on the bottom line, consisting of zig-zag lines. Resistors are pieces of circuit that resist to the flow of current in the circuit.

- Switches: they are labelled with a line with two dots at both ends. They can be opened/closed in order to stop/allow the flow of current in the circuit.

- Light bulbs: they are labelled with a circle filled with a X.

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.
