Question

Assuming force(F) lengthL AND TIMET as fundamental units find dimensions of mass

Answer 1

Explanation:

dimensions for Mass is L^0 M^1 T^0

as unit of mass is kg

Answer 2

Explanation:

F =[MLT-2]

length=[L]

time=[T]

mass=[M]

let

[M]=[MLT-2]^x [L]^y [T]^z

[M]=[M^x L^x T^-2x] [L^y] [T^z]

[M]=M^x L^x+y T^-2x+z

comparing powers

*x=1

*x+y=0

1+y=0

y=-1

*-2x+z=0

-2(1)+z=0

z=2

hence m=F L-1 T2

M=FT^2/L
