the capacitance of a spherical condenser is 1 micro F.if the spacing between two spheres is 1mm, the radious of the outer sphere is

Question

arpit juneja · Answer

C= 4pi*epsilon 1 (1/ri)-(1/ro) ATQ- ro-ri=0.001m ,C=0.000001F 2 putting 2 in 1 therefore ro^2 -ro(0.001) -(9*1000000000*0.000000001) = 0 therefore ro = 3 metres(approx)

ankit singh · Answer

Capacitance of spherical conductor = 4 π ϵ 0 ​ a where a is radius of conductor. Therefore, C = 9 × 1 0 9 1 ​ × 1 = 9 1 ​ × 1 0 − 9 = 0 . 1 1 × 1 0 − 9 F = 1 . 1 × 1 0 − 1 0 F

Capacitance of spherical conductor =4πϵ0a
where a is radius of conductor.
Therefore, C=9×1091×1=91×10−9
=0.11×10−9F=1.1×10−10F
