Answer:
If the particle is an electron ![E_y = 3.311 * 10^3 N/C](https://tex.z-dn.net/?f=E_y%20%3D%203.311%20%2A%2010%5E3%20N%2FC)
If the particle is a proton, ![E_y = 6.08 * 10^6 N/C](https://tex.z-dn.net/?f=E_y%20%3D%206.08%20%2A%2010%5E6%20N%2FC)
Explanation:
Initial speed at the origin, ![u = 3 * 10^6 m/s](https://tex.z-dn.net/?f=u%20%3D%203%20%2A%2010%5E6%20m%2Fs)
to +ve x-axis
The particle crosses the x-axis at , x = 1.5 cm = 0.015 m
The particle can either be an electron or a proton:
Mass of an electron, ![m_e = 9.1 * 10^{-31} kg](https://tex.z-dn.net/?f=m_e%20%3D%209.1%20%2A%2010%5E%7B-31%7D%20kg)
Mass of a proton, ![m_p = 1.67 * 10^{-27} kg](https://tex.z-dn.net/?f=m_p%20%3D%201.67%20%2A%2010%5E%7B-27%7D%20kg)
The electric field intensity along the positive y axis
, can be given by the formula:
![E_y = \frac{2 m u^2 sin \theta cos \theta}{qx} \\](https://tex.z-dn.net/?f=E_y%20%3D%20%5Cfrac%7B2%20m%20u%5E2%20sin%20%5Ctheta%20cos%20%5Ctheta%7D%7Bqx%7D%20%5C%5C)
If the particle is an electron:
![E_y = \frac{2 m_e u^2 sin \theta cos \theta}{qx} \\](https://tex.z-dn.net/?f=E_y%20%3D%20%5Cfrac%7B2%20m_e%20u%5E2%20sin%20%5Ctheta%20cos%20%5Ctheta%7D%7Bqx%7D%20%5C%5C)
![E_y = \frac{2 * 9.1 * 10^{-31} * (3*10^6)^2 *(sin38)( cos38)}{1.6*10^{-19} * 0.015} \\](https://tex.z-dn.net/?f=E_y%20%3D%20%5Cfrac%7B2%20%2A%209.1%20%2A%2010%5E%7B-31%7D%20%2A%20%283%2A10%5E6%29%5E2%20%2A%28sin38%29%28%20cos38%29%7D%7B1.6%2A10%5E%7B-19%7D%20%2A%200.015%7D%20%5C%5C)
![E_y = 3311.13 N/C\\E_y = 3.311 * 10^3 N/C](https://tex.z-dn.net/?f=E_y%20%3D%203311.13%20N%2FC%5C%5CE_y%20%3D%203.311%20%2A%2010%5E3%20N%2FC)
If the particle is a proton:
![E_y = \frac{2 m_p u^2 sin \theta cos \theta}{qx} \\](https://tex.z-dn.net/?f=E_y%20%3D%20%5Cfrac%7B2%20m_p%20u%5E2%20sin%20%5Ctheta%20cos%20%5Ctheta%7D%7Bqx%7D%20%5C%5C)
