A proton moves at 500 105 ms in the horizontal direction

Question

Solve the all parts of following question given below:

Question: A proton moves at 5.00 105 m/s in the horizontal direction. It enters a uniform vertical electric field with a magnitude of 9.00 103 N/C. Ignore any gravitational effects.

Part I: Find the time interval required for the proton to travel 4.00 cm horizontally.

ns

Part II: Find its vertical displacement during the time interval in which it travels 4.00 cm horizontally. (Indicate direction with the sign of your answer.)

mm

Part III: Find the horizontal and vertical components of its velocity after it has traveled 4.00 cm horizontally.

Write your solution in appropriate format and provide references for above question.
