مسأله فيزيا ما عرفت حلها أرجو منكم الرد بأسرع وقت لانه السستم للمسأله راح يصكر الساعه 12




Two charges, -Q_0 and -4Q_0 are a distance L apart. These two
charges are free to move but do not because there is a third charge nearby.

What must be the magnitude of the third charge and its placement in order for the first two to be in equilibrium?

Q= .......... * Q_0


distance =........ L from -Q_0 towards -4Q_0


و شكراااااا ....
