Question

WHAT IS DIMENSIONAL FORMULA OF PERMITTIVITY OF VACUUM

Answer 1

Heya

M^-1 L^-3 T^4 A^2 is the dimensional formula for permittivity of vacuum.

Here M is Mass, L is length, T is time and A is current.


Hope this helps

Answer 2

Answer:

You asked for the dimensional formula for Permittivity of Vacuum…

Explanation:

Now, lets focus on what Permittivity of vacuum is equivalent to, before we get started with calculating its dimensional formula.

Permittivity = (Charge)^2 / (Force) X (Distance)^2

Now replacing each quantity with its basic unit we get,

Charge = (TA)^2.

Force = MLT^-2

Distance = (L)^2

Now replacing back in the equation we get…

Permittivity = (TA)^2 / (MLT)-2 X (L)^2

  = M^-1 L^-3T^4A^2
