Question

A sphere of radius 10cm is charged to a potential of 3*10^4N-C. calculate the outward pull per unit area. ​

Answer 1

Explanation:

Given A sphere of radius 10 cm is charged to a potential of 3*10^4N-C. calculate the outward pull per unit area.  

• We need to find the outward pull.
• Given radius is 10 cm
• So V = 3 x 10^4 V
• So we have pressure = Force / unit area
• So p = ½ εo (v/r)^2
• So p = ½ (8.85 x 10^-12) (3 x 10^4 / 10 x 10^-2 )^2
•       = 39.825 x 10^-2
•      = 0.3982 N / m^2
• Therefore the outward pull per unit area will be 0.398 N/m^2
