Question

18. How much charge can be given to a sphere of radius 1 cm in air
. (Maximum surface density of charge on a conductor in air (0) = 265x
10-5C/m).​

Answer 1

Answer:

sorry

Step-by-step explanation:

i dont know the answer

Answer 2

Answer: 3.33×10-⁸ C

Step-by-step explanation:

Given,

r=1cm or (1×10-²)m

σ=2.65×10-⁵ C/m²

Then,

σ=Q/A [A=Area of surface of Sphere]

Hence, Q=σA

=> Q= (2.65×10-⁵ c/m²)(4πr²)

=> Q= (2.65×10-⁵ c/m²)(4π10-⁴ m²)

=> Q= (33.3×10-⁵×10-⁴) C

=> Q= 33.3×10-⁹ C

=> 3.33×10-⁸ C Answer..

I had seen other two answers they were slightly wrong so i added this answer.

By the way thanks for all your efforts ♥️
