Explanation / Answer

field due to both will be same in magnitude and direction,

( E = k q / r^2)

E = 2 ( k e / (d/2)^2) )

E = 8 ( (9 x 10^9 x 1.6 x 10^-19)/(2.4 x 10^-10)^2)

E = 2 x 10^11 V/m = 2 x 10^5 M V./m

Ans: (D)

towarsd the Cl atom ......Ans

F = k e e / d^2

= (9 x 10^9) (1.6 x 10^-19)^2 / (2.4 x 10^-10)^2

= 4 x 10^-9 N

Ans(D)

eV/A

= (4 x 10^-9)/(1.6 x 10^-19) (10^-10)

= 2.5

Ans(B)
