Question

formula for permittivity in free space

Answer 1

Permittivity =[Ɛo] = [Charge]2 /([Force] [Distance]2) =[TA]2 / [MLT-2] [L]2 {[A] is the dimensional formula of electric charge} =[TA]2 / [ML3T-2] =[M-1L-3T(2+2)A2] = [M-1L-3T4A2] ... Unit of permitivity = Newton x square meter/square kg. Dimensional formula = [MLT^-2][L^2][M^-2]

Answer 2

The permittivity of free space (a vacuum) is a physical constant equal to approximately 8.85 x 10-12 farad per meter (F/m). ... In general, permittivity is symbolized and is a constant of proportionality that exists between electric displacement and electric field intensity in a given ...
