Solving a problem in physics section 73 point 46 electr

46. A ball of mass m = 0.1 g, having a charge q = 9.8 nC, is suspended on a thread in a uniform electric field directed horizontally. Field strength E = 105 V / m. Show that the angle of deviation of the thread from the vertical is determined by the equation tgα = qE / mg, α = π / 4.
