Two small beads having positive charges q=30q and q=q are fixed at the opposite ends of a horizontal insulating rod of length =1.50 m.The bead with charge q is at the origin.As cwn in the fiqgure below, a third sma, charged bead is free to side on the rod 12
x is the third bead in equilibrfum? m
bCan the equitibrium be stable @Yes,if the third bead has a pesitive charge Yes,if the third bead has a negative charge NO
