Answer:
Percentage change in tension is 3.8%
Explanation:
We have given initially frequency
= 440 Hz
Let tension in the string at this frequency is 
Now second frequency is 
Frequency in string is given by

From the relation we can say that


Percentage change in tension is equal to
%
So percentage change in tension is 3.8%
Unbalanced forces is what they are called
If the potential is given by v = xy - 3z-2, then the electric field has a y-component of X
When the charge is present in any form, a point in space has an electric field that is connected to it. The value of E, often known as the electric field strength, electric field intensity, or just the electric field, expresses the strength and direction of the electric field.
Each location in space where a charge exists in any form can be considered to have an electric field attached to it. The electric force per unit charge is another name for an electric field. The electric field's equation is given as E = F / Q. Volts per meter (V/m) is the electric field's SI unit. Newton's per coulomb unit is the same as this one.
