Given fn = n/2? vF/Âµ , if the mass density Âµ of a violin string oflength ? is doubled, how should you adjust the tension F topreserve the same tune?

FN +mg +fk +F=0

FN is the normal force,mg is mass and gravitational acceleration which equals toweight, and F is force. Sowhat is fk? Blah I can't believe I don't know this.

The forces $F_{1}, F_{2}, \dots, F_{n}$ acting at the same point P are said to be in equilibrium if the resultant force is zero, that is, if

F_{1} + F_{2} + \dots + F_{n} = 0

. Find (a) the resultant forces acting at P, and (b) the additional force required (if any) for the forces to be in equilibrium.

\begin{array}{l} F_{1} = 4 i - j, F_{2} = 3 i - 7 j, F_{3} = - 8 i + 3 j, F_{4} = i + j \end{array}

\begin{array}{l} F_{1} = 4 i - j, F_{2} = 3 i - 7 j, F_{3} = - 8 i + 3 j, F_{4} = i + j \end{array}

\begin{array}{l} F_{1} = 4 i - j, F_{2} = 3 i - 7 j, F_{3} = - 8 i + 3 j, F_{4} = i + j \end{array}

\begin{array}{l} F_{1} = 4 i - j, F_{2} = 3 i - 7 j, F_{3} = - 8 i + 3 j, F_{4} = i + j \end{array}
