The solution of the formula for E is given by:
E = 50m/L.
<h3>How to solve an expression for a variable?</h3>
To solve an expression for a variable, we have to isolate the variable.
In this problem, the expression is given by:
L = 50m/E
Hence we do the operations to isolate E, as follows:
LE = 50m
E = 50m/L.
