Explanation / Answer

Electric force= qE

a) Electric force on ( X component) on proton = 1.6 x 10^-19. ( 900i) = 1440 x 10^-19 N

b) Electric force on ( Y component) on proton = 1.6 x 10^-19. (500 j) =800 x 10^-19 N

c)  Electric force on ( X component) on electron= - 1440 x 10^-19 N

d)  Electric force on ( Y component) on electron = - 800 x 10^-19 N

e) net force on proton = sqroot ( 1440 x 10^-19 ^ 2 + 800 x 10^-19 ^2) = 1647 x 10^-9 N

accelation= f/m= 1647 x 10^-9/ 1.6726219 × 10-27= 984.86 x 10^ 18 m/s^2

f) net force on electron = - 1647 x 10^-9 N

acceleration = 1647 x 10^-9/9.10938356 × 10-31 = 180.8 x 10^22 m/s^2 apprx
