Ap physics b two identical charges 6.5 microcoulmbs are attached to a string, find the tension of the string.

Answer :

To calculate the tension in a string holding two identical charges, one would use Coulomb's Law to find the electrostatic force and then analyze the equilibrium of forces. The distance between the charges or the length of the string is required to calculate the actual tension, which was not provided in the question.

To find the tension in the string holding two identical charges, we need to use Coulomb's Law to determine the electrostatic force between the charges and then analyze the forces in the context of a force-diagram. For two charges of 6.5 microcoulombs (6.5 × 10−6 C) each, Coulomb's Law gives us the magnitude of the electrostatic force (Fe) as:

Fe = k × (q1 × q2) / r2

Where k is Coulomb's constant (8.99 × 109 N·m2/C2), q1 and q2 are the charges, and r is the distance between the charges. To find the tension, we would then create a force-diagram to show the tension counteracting the horizontal component of electrostatic force when considering the equilibrium of forces. The question, however, doesn't provide the length of the string or the distance between the charges, which is necessary to calculate the actual tension.

Without this additional information, we cannot provide a numerical answer for the tension. Assuming the charges hang at an angle at rest, the tension in the string would be the horizontal component of the electrostatic force. If you can provide the distance between the charges or the length of the string, the exact tension in the string could be calculated.
