Q. Example

16

.

5

\newline

Given that

R=2, d=4

and

L=16

, find the value of

K

, if

K=\frac{R d^{2}}{L}

Given Values: We are given: $\newline$ $R = 2$ $\newline$ $d = 4$ $\newline$ $L = 16$ $\newline$ Expression to find: $K = \frac{Rd^{2}}{L}$ $\newline$ Identify the expression after substituting the values of $R$ , $d$ , and $L$ . $\newline$ Substitute $2$ for $R$ , $4$ for $d$ , and $d = 4$ $1$ for $L$ in the expression $d = 4$ $3$ . $\newline$ $d = 4$ $4$
Calculate Square of $d$ : Calculate the square of $d$ . $\newline$ $(4)^{2} = 4 \times 4$ $\newline$ $= 16$
Substitute $d^2$ : Substitute the value of $d^{2}$ into the expression. $K = \frac{2 \times 16}{16}$
Simplify Expression: Simplify the expression by multiplying $2$ and $16$ . $2 \times 16 = 32$ $K = \frac{32}{16}$
Divide to Find K: Divide $32$ by $16$ to find the value of $K$ . $\newline$ $\frac{32}{16} = 2$ $\newline$ $K = 2$
