An electron is placed in a constant electric field, E = 2.2 x 1013j 8. The electron is given an initial velocity of v = 1.5î m. a. Calculate the acceleration that the electron experiences. b. Calculate the time that it takes for the electron to move 1.0m in the -j direction. c. After the time in part b has elapsed, where is the electron relative to its starting position?

3. Consider the particle trajectories shown in the uniform and constant electric field. Which trajectory is the correct one for the electron with initial velocity that is shown? W

A positively charged particle of mass 1.92 x 10-27 kg initially moves left to right long the x axis at a speed of 4.02 x 103 m/s. It moves into an electric field, which points in the negative x direction, and travels a distance of 0.41 m before coming to rest. What acceleration magnitude does the particle experience? (Ignore gravity) Round your answer to 2 decimal places.

— Your answer is partially correct. Multiple-Concept Example 3 provides some pertinent background for this problem. Suppose a single electron orbits about a nucleus containing two protons (+2e), as would be the case for a helium atom from which one of the naturally occurring electrons is removed. The radius of the orbit is 2.92 × 10-¹1 m. Determine the magnitude of the electron's centripetal acceleration. Number i 5.9E23 Units m/s^2
