Question

dimensional formula of "Energy density"

Answer 1

Energy Density = Energy/Volume

= (Energy)/(Volume)

= (Force)(Displacement)/(Volume) [As Energy or Work is product of Force and Displacement]

= (Mass)(Acceleration)(Displacement)/(Volume) (As Force is product of Mass and Acceleration)

= ([M][LT^(-2)][L])([L^3])

= [ML^(-1)T^(-2)]

Hope it helps!
thank u

Answer 2

Energy density = Energy/Volume.
Therefore, it's dimensional formula will be:
ML^-1T^-2
