Question

Nine different charged balls, which we treat as point charges, are arranged in a highly symmetric pattern around a square. Note that the value or 2 is 2.00 × 10-6 c, and L-60.0 cm. 20 5g 30 2I. +20 s Ca) what is the magnitude of the net force experienced by the ball with the +Q charge at the center af the square, due to the other g charged balls? For the rest of this problem, we will consider the forces acting on the ball of charge-30. b) Select the two correct statements from the six statements below. Note that you must saloct bath correct statements, and no incorrect stataments, to get credit for the qucction. Wc'll consider first the forca axerted on the ball of chargc -30 y the ball of charge at the top of the square, and then compare it to the force exerted on the ball of charge y the ball cf charge at the top let of the square. The 3Q charge exerts a larger magnitude force on the 20 charge than the 12Q charge exerts on the -30 charge. -Tha-3Q charna exarts a Amaller magnitude fonce on the +2Q charge than the +7Q charga exerts nn the-3Q charge. the-3Q chary: exerts a force on the一2Q charge that has the same magnitude as the force the +2Q charge exerts on the-ЗО charge. ■ The magnitude of the rorce exerted on the IQ charge by the ' 2Q charge at the top is larger than the magnitude of the rorce exerted on the 3Q charge by the 5Q charge at the too lert. The magnitude of the force exerted on the -34 charge by the +20 cherge at the top is smaller than the magnitude of the force exertedon the -30 charge by the-5Q chare at the top left. Tna magnitude nf tha fnrca ㅋxarted nn the-30 cnarna hy the +2Q charna at the top i..gual to tna magnituda nf the fora axarted on the _3Q charna ny the-SQ charge at the top left. (c What is the magnitude of the net force experienced by the ball with the 3 charge due to the 3 and tQ charged balls only? d) What is the magnitude of the net force experienced by the bll with the 3 charge due to the tour charged balls with charçes of507 Ce) what is the magnitude of the net force experienced by the ball with the 3 charge due to the two charged balls with charges of 20? ) use your previous three results to find the magnitude of the net rorce experienced by the ball with the 3Q charge due to the other อ charged balls
