Explanation / Answer

Given,

q = -343e ; r = 6.6 cm ; theta = 69 deg ;

a)we know that

lambda = q/L

L = r (theta) = 0.066 x 69 x 3.14/180 = 0.079 m

lambda = -343 x 1.6 x 10^-19/0.079 = -6.95 x 10^-16 C/m

Hence, lambda = -6.95 x 10^-16 C/m

b)Now simga = q/Area

sigma = -343 x 1.6 x 10^-19/(3.14 x 0.022^2) = -3.61 x 10^-14 C/m^2

Hence, sigma = -3.61 x 10^-14 C/m^2

c)sigma = q/A

sigma = -343 x 1.6 x 10^-19/4(3.14 x 0.048^2) = -1.89 x 10^-15 C/m^2

Hence, sigma = -1.89 x 10^-15 C/m^2

d)rho = q/volume

rho = 343 x 1.6 x 10^-19/(4/3 x 3.14 x 0.035^3) = -3.06 x 10^-13 C/m^3

Hence, rho = -3.06 x 10^-13 C/m^2
