In a given crt, electrons are accelerated horizontally by 7.0kv . they then pass through a uniform electric field e for a distance of 2.4cm , which deflects them upward so they travel 24cm to the top of the screen, 10cm above the center. Estimate the value of E. Neglect the upward distance that electron moves while in the electric field.
