A positively charged bead having a mass of 1.00 g falls from rest in a vacuum from a height of 7.50 m in a uniform vertical electric field with a magnitude of 1.00 multiplied by 104 N/C. The bead hits the ground at a speed of 26.1 m/s.
(a) Determine the direction of the electric field.
(b) Determine the charge on the bead.
