Ideal for giving your kitchen or bathroom that streamlined and urban look. "To the left, on a rock nearer the railway, are the remains of the Cachticz, Hungar.Csejthe, once the residence of the infamous Elizabeth Bathory, who is said to have caused upwards of 300 young girls to be murdered within ten years for the purpose of restoring herself to youth by means of their blood.She was afterwards thrown into prison, where she died in 1610." MathJax reference. B. balls 1 and 3 carry charges of the same sign; ball 2 carries a charge of the opposite sign. Note that Newton's third law (every force exerted creates an equal and opposite force) applies as usualthe force on is equal in magnitude and opposite in direction to the force it exerts on . The hanging ball should be centered on a line with the sliding balls. Problem 2 Easy Difficulty. What is the charge on the pith balls?
