Question

Which of the following equations is dimensionally incorrect?
Where,

t

= time,

h

= height ,

s

= surface tension,

\theta

= angle,

\rho =

density,

a,r

= radius,

g

= acceleration due to gravity,

V

= Volume,

P

= presssure,

W

= Work done,

\tau =

torque,

\varepsilon =

permittivity,

E

= Electric field,

J

= Current density,

L

= length

Accepted Answer

$V\, = \,\frac{{\pi p{a^4}}}{{8\eta L}}$

Answer

$h = \frac{{2s\,\cos 	heta }}{{ho rg}}$

Answer

$J\, = \,\varepsilon \,\frac{{\partial E}}{{\partial t}}$

Answer

$W\, = \,	au 	heta $
