Answer 2

Answer:

please mark me brain list

Explanation:

answer : (i) 2.6 × 10^5 N/C (ii) 1.3 × 10^5 N/C

It has given that two charges +10μC and

-10μC are seperated 5mm apart.

so, dipole, P = qd

= 10μC x 5mm

= 10 x 10^-6 C × 5 × 10^-3 m

= 5 x 10^-8 Cm

(i) electric field at a point on axial line, E = 2KP/r³

= (2 × 9 × 10^9 × 5 × 10^-8)/(15 × 10^-2)³ [ here, r = 5cm ]

X

(90 × 10)/(3375 × 10^-6)

= 0.266 × 10^6= 2.66 × 10^5 N/C

(ii) electric field at a point on equatorial line, E = KP/r³

= (9 × 10^9 × 5 × 10^-8)/(5 × 10^-2)³

- (45 × 10)/(3375 × 10^-6)

= 0.133 × 10^6 = 1.33 × 10^5 N/C
