## Homework Statement

On the diagram, a charged particle of charge 0.000003 C and mass 0.000007 kg moves across the

electric field 6760 V/m with initial speed 40 m/s. When its x coordinate is 93.3 cm, its y coordinate is (in cm)?

## Homework Equations

y=(e*Em*x^2)/(2*m*v^2), where Em is electric field, m is mass and v is speed.

## The Attempt at a Solution

Using the equation given, I plugged in all the variables y=(0.000003*6760*93.3)/(2*0.000007*40^2) which gave me 7881 which is not correct. What am I doing wrong? Should I be plugging the charge of an electron (1.60*10^-19)? I'm almost positive this is the equation I need to use to figure it out. Any help would be much appreciated.
