    Physics problems

    electric feild (E)= V/d and also E=F/q where V is the p.d., d is the distance bw 2 plates, F is the force on the charge and q is the charge. so first u find E=V/d (make sure ur d is in metres!) so E= 250/ (7.6/1000) E= 32900 V/m then E= F/q F=E q *chrge of an electron is 1.6*10^-19 C 32900 *...
