Answer to Question #181770 in Field Theory for aliah escano

Question

1.   A square metal plate with a length of 0.20 m and with a charge of 9.7 x 10 ^-7 C. Find the electric field of the square metal plate. 

Answer 1

Answer

Electric field due to square plate

$E=\frac{\sigma }{2\epsilon _0}\\=\frac{q}{2A\epsilon _0}\\=\frac{9.7\times10^{-7}}{2\times0.2\times0.2\times8.85 \times10^{-12} }\\=1.4\times10^{6}N/C$
