(F )x =1.12×1016 N
Explanation / Answer
q = 1.6x10^-19 C
Mp = 1.67x10^-27 kg
Me = 9.11x10-31 kg
F = qE = 1.6x 10-19 (700 i + 900 j )
= 1.12 x 10-16 i + 1.44 x10-16 N
x - compo = 1.12 x 10-16 N
y -compo = 1.44 x10-16 N
on electron magnitude will be same just opposite direction
x-compo = - 1.12 x 10-16 N
y -compo = - 1.44 x10-16 N
magnitude of force = sqrt(x^2 + y^2) = 1.82 x 10-16 N
a_proton = F/ mass = 1.82 x 10-16 / 1.67 x10-27 = 1.09x 10^11 m/s2
a_electron = F/mass = 1.82 x 10-16 / 9.11 x10-31 = 2 x 10^14 m/s2
