we know that,
f=ma
=> m=f/a
=> m=fv/t -> 1
since S.I unit of mass is N-M/S³
dimenson of mass is (NLT⁻³)
f=ma
=> m=f/a
=> m=fv/t -> 1
since S.I unit of mass is N-M/S³
dimenson of mass is (NLT⁻³)

srry in my ans i wrote (NLT-3)IT WAS (NLT-2)

Velocity=distance/time dimension of velocity=LT-1 Force=mass x accelaration accelaration =velocity/time dimension of accelaration=LT-1/T =LT-2 Force=mass x accelaration mass=force/accelaration dimension of mass=dimensionofforce/dimension of accelaration =MLT-2/ LT-2=M DIMENSION OF MASS=M
