Question

the dimensipnal formula of a physical quantity is M^a L^b T^c . then the physical quantity is ?​

Answer 1

Answer:

ANSWER

1) Surface Tension [S]=

Length[L]

Force[F]

So, S=

[L

1

]

[M

1

L

1

T

−2

]

∴ Surface Tension =S=[M

1

L

0

T

−2

]

2) Force [F]= mass (m) × acceleration (a)

=[M

1

]×[L

1

T

−2

]

F=[M

1

L

1

T

−2

]

3) Angular frequency =w=

sec[dt]

red[dϕ]

w=[M

0

L

0

T

−1

]

4) Spring constant [K]=

Extension of spring[x]

Force applied[F]

=

[L

1

]

[M

1

L

1

T

−2

]

K=[M

1

T

−2

]

K=[M

1

L

0

T

−2

]

∴ Option C is correct.
