given
x = 0.16 m
y = 0.25 m
r = ( 0.162 + 0.252 )1/2
r = 0.296 m
the electric potential is V = k ( ( - 3.3 x 10-6 / 0.25 ) + 2.7 x 10-6 / 0.16 + ( -6.1 x 10-6 / 0.296 ) )
= 9 x 109 x ( ( - 3.3 x 10-6 / 0.25 ) + 2.7 x 10-6 / 0.16 + ( -6.1 x 10-6 / 0.296 ) )
= 9 x 103 x ( ( - 3.3 / 0.25 ) + 2.7 / 0.16 + ( -6.1 / 0.296 ) )
= 9 x 103 x ( - 13.2 + 16.875 - 20.608 )
V = - 152397 volts

Show all work. Assume k = 8.99 x 10^9 N m^2/C^2. In the x-y plane, a point object with electric charge 3.03 mC and mass 9.450 grams in traveling in the +x direction with a constant speed of 12.6 ms^-1. At x=0, it enters a region where the electric field is in the direction of the +y axis and has constant strength of 2.59x10^3 N C^-1. After 16 seconds in this region, what is the magnitude and direction of the...
