Part A: What is the acceleration of an electron that is placed in a uniform electric field of 7200 N/C pointing in the +y-direction? Find the magnitude of the acceleration. Express your answer to four significant figures and include the appropriate units. Part B: Find the direction of the acceleration.
1) pointing in the +y-direction
2) pointing in the -x-direction
3) pointing in the -y-direction
4) pointing in the +x-direction
