Two charges Q1=20ụC and Q2=22µC are placed on the corners of a rectangle with the sides a=14mm and b=27mm. How much work must be done to bring a third charge Q3=9µC from infinity to point P that is a distance c=0.48b away from Q1 as shown in the figure below. Express your answer in units of Joules using zero decimal places. Take Coulomb constant as k=9.0x10° N.m2/c2. Please do not forget the minus sign if your answer is negative. Q1 C »P а 'Q2

Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”
