Question

place another charged ball Qo on the line between the two will be zero? Two balls with charges+Q and +40 are fixed at a separation distance of 3R. Is t possible to charges such that the net force on Q a) Yes, but only if Qo is positive, Yes, but only if Qo is negative Yes, independent of the sign (or value) of Q No, the net force can never be zero 2. Two particles, each with charge Q, and a third particle Wilth ohucie with charge a vertices of an equilateral triangle as shown. The total force on the q are placed at the The total force on the particle with charge q A) parallel to the left side of the triangle, B) parallel to the right side of the triangle, C) paralilel to the bottom side of the triangle,erpendicular to the bottom side of the triangle, E) perpendicular to the left side of the triangle 3. A charge Q is transferred from an initially uncharged plastic ball to an identical ball, if the total charge of the second ball is-80 x 10". С How many electrons were transferred from one ball to the other? Nofe 4 2 A 40-pC charge is positioned on the x axis at x = 4 0 ㎝ Where should a-60-C charge be placed to produce a net electric field of zero at the origin? a.-5.3 cm b. 5.7 cnm 4.9 cm d. -6.0 cm +6.0 cm
