Question

Two parallel large thin metal plats have equal surface charge densities (s = 26.4 × 10^–12 c/m²) of opposite signs. The electric field between these plates is–

• A. 1.5 N/C
• B. 1.5 × 10^–10 N/C
• C. 3 N/C
• D. 3 × 10^–10 N/C

Answer 1

Answer: (C)

3 N/C

Answer 2

E_net = E₁ + E₂

= $\frac { \sigma } { 2 \varepsilon _ { 0 } }$+ $\frac { \sigma } { 2 \varepsilon _ { 0 } }$ = $\frac { \sigma } { \varepsilon _ { 0 } }$
