In a relation $\color{#D61F06}{F}$ = $a\sin(k_1\color{#456461}{x})$ + $b\sin(k_2\color{#0C6AC7}{\text T})$ where $F, x$ and $T$ denote the $\color{#D61F06}{\text {force}} , \color{#456461}{\text {distance}}$ and $\color{#0C6AC7}{\text{ Time}}$ respectively. Units of $\color{magenta}{k_1}$ and $\color{magenta}{k_2}$ respectively in S.I units are.
