1.	Two charges + 2 micro coulomb and +8micro coulomb are separated by adistance 10cm apart in air where should a thirdcharge tshic be placed so that the charge is inequilibriumAlso and intensity of electric field at a point medwayb/w the charges.
Answer» Answer: Given conditions ⇒ q₁ = 12 μC = 12 × 10⁻⁶ C. q₂ = 8 μC = 8 × 10⁻⁶ C. Distance between them(r₁) = 10 cm. = 0.1 m. Final Distance between them(r₂) = 6 cm . = 0.06 m. Work done in bringing the charges UPTO the distance of 6 cm is given by, W = K q₁ q₂ (1/r₂ - 1/r₁) = 9 × 10⁹ × 12 × 10⁻⁶ × 8 × 10⁻⁶(1/0.06 - 1/0.1) = 864 × 10⁻³ (16.67 - 10) = 864 × 10⁻³(6.67) = 5760 × 10⁻³ = 5.76 J.

Answer»

Answer:

Given conditions ⇒

q₁ = 12 μC = 12 × 10⁻⁶ C.

q₂ = 8 μC = 8 × 10⁻⁶ C.

Distance between them(r₁) = 10 cm. = 0.1 m.

Final Distance between them(r₂) = 6 cm . = 0.06 m.

Work done in bringing the charges UPTO the distance of 6 cm is given by,

W = K q₁ q₂ (1/r₂ - 1/r₁)

= 9 × 10⁹ × 12 × 10⁻⁶ × 8 × 10⁻⁶(1/0.06 - 1/0.1)

= 864 × 10⁻³ (16.67 - 10)

= 864 × 10⁻³(6.67)

= 5760 × 10⁻³

= 5.76 J.
