F = 153 N

Explanation:

Let us define first our directional convention. Anything pointing up or to the right is considered positive and anything pointing down or to the left is considered negative. Now let's look at the components and :

= 350 N - 200 N = 150 N

= 180 N - 150 N = 30 N

The magnitude of the resultant force F is given by

To find the direction , we use

or

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
