hello mate
pls follow me.... ni
DIMENSIONAL FORMULA OF SURFACE TENSION =M T^-2
UNIVERSAL GRAVITATIONAL CONSTANT=M^-1 L^3 T^-2
IMPULSE=M L T^-1
TORQUE=M L^2 T^-2
the dimensional equation of surface tension is
T=
=
=
=M T^-2
the dimensional formula of universal constant of gravitation
G=
=
=M^-1 L^3 T^-2
the dimensional formula of impulse is given by
I=F*T
=M L T^-2 T
=M L T^-1
the dimensional formula of torque is given by
tau=F *R
=M L T^-2 L
=M L^2 T^-2
