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.
