An electric field of 106 n/c acts on an electron, resulting in an acceleration of 1.3 ✕ 1017 m/s2 for a short time. what is the magnitude of the radiative electric field observed at a location a distance of 4 cm away along a line perpendicular to the direction of the acceleration?

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
