9) A charge of 20.0 nC is located inside a sphere, 125 an fron its center. What is the electric flux through the sphere due to this charge? (E0-885 × 10-12 C2/N·m2) A) 0.11 N. m2/C B) 226 N m2/C C) 2260 N m2/C

Solution

12.

KE = change in PE

=> 1/2mv^2 = eV

=> v = sqrt ((1.6*10^-19*160*10^3*2)/(9.1*10^-31)) = 237199781.33 = 2.4*10^8 m/s   ( option C )

9)

flux = q/apsalan = 20*10^-9)/(8.85*10^-12) = 2259.887 N.m^2/C ( option C )
