Final answer:
The potential energy of electrical interaction between two point charges can be calculated using the formula U = k * q1 * q2 / r, where U is the potential energy, k is the Coulomb constant, q1 and q2 are the charges, and r is the distance between the charges. Based on this formula, the potential energy of interaction between the -5×10^-5 C and -6×10^-5 C point charges 1m apart is 2.7 J.
Step-by-step explanation:
The potential energy of electrical interaction between two point charges can be calculated using the formula:
U = k * q1 * q2 / r
Where U is the potential energy, k is the Coulomb constant (9 × 10^9 N m^2/C^2), q1 and q2 are the charges, and r is the distance between the charges.
Using this formula, the potential energy of interaction between the -5×10^-5 C and -6×10^-5 C point charges 1m apart is:
U = (9 × 10^9 N m^2/C^2) * (-5×10^-5 C) * (-6×10^-5 C) / 1m
Calculating this expression gives a potential energy of 2.7 J.
