TP 20.6

(a)    Given: E = 1.20 x 10⁵ V/m 

Ds = 0.750 mm = 0.750 x 10^-3 m 

Find: DV - ? 

DV = -E Ds = -(1.20 x 10⁵ N/C )( 0.750 x 10^-3 m ) = - 90.0 V

(b)    Given: E = 2.40 x 10⁴ V/m 

Ds = 0.750 mm = 0.750 x 10^-3 m 

Find: DV - ? 

DV = -E Ds = -(2.40 x 10⁴ N/C )( 0.750 x 10^-3 m ) = - 18.0 V
