Compute each part of given question:
Question: An electron is initially at rest and is accelerated in the positive x direction to a speed of 1.14 × 106 m/s over a distance of 2.8 cm, by a uniform electric field.
Part A: Which direction could the electric field point to produce this acceleration?
Part B: What is the magnitude of the electric field? (Hint: Use kinematic equations and Newton's second law. Gravity can be neglected)
Please show your results in detailed calculations.
