An electron is traveling through a uniform electric field. The field is constant and given by E⃗ =(2.00×10−11N/C)i^−(1.20×10−11N/C)j ^. At t=0 , the electron is at the origin and traveling in the x direction with a speed of 2.10 m/s .

X-Coordinate=2.24m

Y-Coordinate=3.42m

Explanation:

Acceleration in the x-direction = E (e/m) =(-) 2e-11*1.758e11 = -3.516 m/s^2

Distance moved in the x-dirction = ut + 1/2at^2

Putting values in above equation,

(2.1*1.8) - (0.5*3.516*1.8*1.8) = 2.24m

Acceleration in the y-direction = E(e/m) = (-)*(-) 1.2e-11*1.758e11 =+ 2.1096m/s^2

Distance moved in the Y-dirction = ut +1/2at^2

Putting values in the above equation,

0+ 0.5*2.1096*1.8*1.8 = 3.42m

So,

Coordinates are (2.24m, 3.42m)

we need to know the time interval during which the force acts. impulse of force = momentum change
