In the equation y=a sin(?t+kx),the dimensional formula of ? is
Options
(a) [M⁰L⁰T⁻¹]
(b) [M⁰LT⁻¹]
(c) [ML⁰T⁰]
(d) [M⁰L⁻¹T⁰]
Correct Answer:
[M⁰L⁰T⁻¹]
Explanation:
Angle is dimension less quantity. So the argument (?t-kx) is a dimension less. Therefore, ?t as well as kx are also dimension less.
Dimension of t is T. So dimension of ? must be T⁻¹
