A charged particle of mass m and charge q is at rest. It is accelarated in a uniform electric field of intensity E for time t. What is the kinetic energy of the particle after time t ?

Dear student .... Here , initial velocity = 0, F=qE ...ma=qE .... therefore , a=qE/m.....v=u+at ...v=(qE/m)t...... Kinetic energy= 1/2mv²=1/2m(q²E²t²/m²)= q²E²t²/2m.....With regards....Mahima... ( askiitians forum expert)
