Answer: Dimensions of A are of length [L]
Dimensions of B are of
Dimensions of C are of
Step-by-step explanation:
The given equation is
Since the dimension on the L.H.S of the equation is [L] , each of the terms on the right hand side should also have dimension of length[L] to be dimensionally valid
Thus
Dimensions of A = [L]
Dimensions of Bt = [L]
Similarly
Dimensions of
Divide by the coefficient of e^2, then take the square root.
e^2 = 49/(9f)
e = ±7/(3√f) = ±(7√f)/(3f)
The 3rd selection is appropriate:
e=±(7√f)/(3f)
______
When written in plain text (not typeset), any denominator containing arithmetic must be enclosed in parentheses. When the expression is typeset, the surd and the division bar do the grouping for you.
