Answer:
10.22 cm
Explanation:
linear charge density, λ = 7.5 x 10^-12 C/m
distance from line, r = 14.5 cm = 0.145 m
initial speed, u = 3000 m/s
final speed, v = 0 m/s
charge on proton, q = 1.6 x 10^-19 C
mass of proton, m = 1.67 x 10^-27 kg
Let the closest distance of proton is r'.
The potential due t a line charge at a distance r' is given by
where, K = 9 x 10^9 Nm^2/C^2
W = q V
By use of work energy theorem
Work = change in kinetic energy
By substituting the values, we get
r' = 14.5 x 0.7047 = 10.22 cm
