Free webinar on Robotics (Block Chain) Learn to create a Robotic Device Using Arduino
30th Jan @ 5:00PM for Grade 1 to 10
The ratio of forces between two small spheres with constant charge in air to that in a medium of dielectric constant K? The ratio of forces between two small spheres with constant charge in air to that in a medium of dielectric constant K?
Force due to charge in air = > q1q2/(4*pi*e)r^2 = F1Force due to charge in di – electric medium = F2orF2 = q1q2/(4*pi**e*K)r^2where K is the dielectric constant.Dividing the forces we get,F1/ F2 = K
