Given,
q = 3.1 x 10^-16 C ; E = 3.55 i N/C ; r = 15 cm ; theta = 15 deg
a)The expression will be:
Fx = q E
magnitude will be:
Fx = 3.1 x 10^-16 x 3.55 = (1.1 x 10^-15 N)i
b)Force along Y will be zero since there is no electric field along y direction
Fy = 0
c)F = sqrt (Fx^2 + Fy^2)
lFl = sqrt [(1.1 x 10^-15)^2 +0^2] = 1.1 x 10^15 N
Hence, lFl = 1.1 x 10^-15 N
