Cumulative Problem 17 The electric field is zero everywhere except in the region

Question

Cumulative Problem 17 The electric field is zero everywhere except in the region oK2.00 cm, where there is a uniform electric field of 100 N/C in the y direction. A proton is moving in the +x direction with a speed of v 1.00x106 m/s. When the proton passes through the region 0x2.00 cm, the electric field exerts a force on it. 1) When the x coordinate of the proton's position is 2.00 cm, what is the x component of its velocity?

Explanation / Answer

1) in x direction, there is no acc so velocity will remain constant in this direction.

v = 1.00 x 10^6 m/s

2) t = x / v0 = 0.02 m / (1 x 10^6 m/s) = 2 x 10^-8 sec

ay = Fe / m = q E / m

ay = (100 x 1.6 x10^-19)/(1.67 x 10^-27)

ay = 9.58 x 10^9 m/s^2

vy = v0y + a t

vy = 0 + (9.58 x 10^9 x 2 x 10^-8)

vy = 192 m/s

3) y = v0y t + ay t^2 / 2

y = 0 + (9.58 x 10^9)(2 x 10^-8)^2 / 2

y = 1.92 x 10^-6 m or 1.92 um

4) after x = 2 cm, there is no field.

hence vy = 192 m/s

5) t = (0.10 - 0.02)/(1 x 10^6)

t = 8 x 10^-8 sec

y = (1.92 x 10^-6) + (192 x 8x 10^-8)

y = 17.3 x 10^-6 m Or 17.3 um
