Homework Help: physics

Posted by Rachel on Tuesday, April 5, 2011 at 10:19pm.

An accelerating voltage of 2.46 * 10^3 V is applied to an electron gun, producing a beam of electrons originally traveling horizontally north in vacuum toward the center of a viewing screen 34.0 cm away.

What is the magnitude of the deflection on the screen caused by the Earth's gravitational field?

I am using this formula
v = squareroot(-2*q*V/m) to find speed and then B = mv/er for the magnitude

but they are asking the answer to be in meters...
