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 26cm to the top of the screen, 12cm above the center.

Estimate the value of E . Neglect the upward distance that electron moves while in the electric field.

Express your answer using two significant figures and include the appropriate units.
