A 5.00 kg block carrying a chargeQ = 40.0 µC is connected toa spring for which k = 100 N/m. The block lies on africtionless horizontal track, and the system is immersed in auniform electric field of magnitude E = 5.00 multiplied by 105 V/m, directed as shown inFigure P16.9.

Figure P16.9

(a) If the block is released at rest when thespring is unstretched (at x = 0), by what maximum amountdoes the spring expand?
1 m
(b) What is the equilibrium position of the block?
2 m
