(A) 1.39 × 10-11 C
(B) 1.39 × 1011 C
(C) 13.9 × 10-11 C

Correct option is: (A) 1.39 × 10-11 C
Correct answer is (C) two parallel plates
B) 1.602 × 10-19C
Given: q = 10 µC = 10 × 10-6 C, F = 16 × 10-4 N To find: Electric field intensity (E) Formula: E = \(\frac{F}{q}\) Calculation: From formula, E = \(\frac{16\times10^{-4}}{10\times10^{-6}}\) = 160 N/C
(B) energy is used from some outside source
Correct option is: (D) 1000 V
Correct option is: (A) 1500 NC-1
Correct option is: (D) 2 µC
(B) radially outward, radially inward
Correct option is: (B) pE sinθ
