My Notes A helium nucleus of mass m = 6.64 × 10-27 kg and charge q = 6.41 × 10-19 C is in a constant electric field of magnitude E = 4.50 x 10-3 N/C pointing in the positive x- direction. Neglecting other forces, calculate the nucleus' acceleration and its displacement after 1.00 s if it starts from rest. (Indicate the direction with the sign of your answer. HINT Find the acceleration using the relation between electric field and electric force, combined with Newton's second law. Then find the displacement using kinematics. Click the hint button again to remove this hint. (a) the nucleus' acceleration (in m/s) m/s (b) its displacement (in m) Need Help? Lead" Lwenn Watch It 7. 2 points SerCP11 15.P028. My Notes A particle of mass 2.10 × 10-9 kg and charge 3.00 pC is moving in a vacuum chamber where the electric field has magnitude 1.90 × 103 N/C and is directed straight upward

Explanation / Answer

A) Acceleration of particle

a= qE/m= 6.41*10-19*4.5*10-3/ (6.64*10^-27)= 4.34*105 m/s2

B) s= 0.5 a t2= 0.5 * 4.34*105* 1= 2.17*105 m
