A charge Q is place at each of the opposite corners of a square. A charge q is placed at each of the other two corners. If the net electrical force on Q is zero, then Q//q equals:

A charge Q is place at each of the opposite corners of a square. A charge q is placed at each of the other two corners. If the net electrical force on Q is zero, then Q//q equals:

A charge Q is place at each of the opposite corners of a square. A charge q is placed at each of the other two corners. If the net electrical force on q is zero, then q//Q equals:

A charges Q is placed at each of the two opposite corners of a square. A charge q is placed to each of the other two corners. If the resultant force on each charge q is zero, then

A charges Q is placed at each of the two opposite corners of a square. A charge q is placed to each of the other two corners. If the resultant force on each charge q is zero, then

A charges Q is placed at each of the two opposite corners of a square. A charge q is placed to each of the other two corners. If the resultant force on each charge q is zero, then

A charge Q is placed at each of the two opposite corners of a square, A charge q is placed at each of the two other opposite corners of the square. If the resultant electric force field on Q is zero, then how Q and q are related ?
