Anegative charge of -0.590 μc exerts an upward 0.600-n force on an unknown charge that is located 0.300 m directly below the first charge. what is the value of the unknown charge (magnitude and sign)?

To calculate the value of unknown charge, we use the formula the electric force between two charges

Here, q is unknown charge ,  ,   and

Now substituting the given values in above formula we get

or

The unknown charge is positive because the force between charges is attractive.

it is a negative acceleration

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
