two 200 pound lead balls are separated by a distance 1m. both balls have the same positive charge q. what charge will produce an electrostatic force. between the balls that is of the same order of magnitude as the weight of one ball?

The  charge is  

Explanation:

From the question we are told that

     The mass of each ball is  

       The distance of separation is  

Generally the weight of the each ball is mathematically represented as  

where g is the acceleration due to gravity with a value

substituting values

Generally  the electrostatic force between this balls is mathematically represented as

given that the the charges are equal we have

So

Now from the question we are told to find the charge when the weight of one  ball is equal to the electrostatic force

So  we have
