I don't know why 6.0 or 6.1 is not the answer.

I found solutions on the Chegg but all solutions gave me an answer 6.0 or 6.1 which is not correct..

Electric Fie Tipler6 21.P.058. Optional Interactive Examp Zero An electron with kinetic energy of 6 x 1016 J is moving to the right along the axis of a cathode-ray tube as shown below There is an electric field E - (2 x 10 N/c) j in the region between the deflection plates.

Explanation / Answer

Solution:-

b) = tan-1[(-eEy)(x)/(2)(K.E)]

=  tan-1(-1.6*10^-19 * 2*10^4*(0.04)/2*(6*10^-16) deg0

= -6.088 deg0
