The frequency for a given number of antinodes, n, in a string is given by , where is the length of the string. If the Tension in the string is , the linear mass density of the string is , the length of string is , and number of antinodes is equal to 1, what is the frequency of the wave

Iwould have to say sorry i can't elaborate more. hope this though!

Answerstatic electricity shock;

The answer is 4f======since electrostatic force is given by    we let f be the electrostatic force when  r = 1 m    if we let  denote the electrostatic force when the distance is decreased so that r = 0.5m, then    we established earlier that f = kq₁q₂. therefore    the force will now be 4f.
