Question

आयतन आवेश घनत्व की विमा क्या होती है? 1 [AL-3T] 2 [A2L-T] 3 [ALT] 4 [AL-3 T] 11:41​

Answer 1

Given : आयतन आवेश घनत्व  

volume charge density

To Find :  Dimensional formula

विमा

[AL⁻³T]  

[A²L⁻¹T]

[ALT]

[AL⁻³ T]

Solution:

volume charge density   is charge present per unit cubic volume .

Unit of charge is Coulomb

Volume unit = m³

volume charge density  = Coulomb / m³

Now Current = Charge ./ Time    I = Q/t

=> Charge = Current * Time

volume charge density  =Current * Time/ m³

Current Dimension = A

Time Dimension =  T

Volume Dimension =  L³

volume charge density  = AT/L³

= ATL⁻³

= AL⁻³T

आयतन आवेश घनत्व की विमा  = AL⁻³T

volume charge density  Dimensional formula = AL⁻³T
