Answer:
Explanation:
The electrostatic potential energy for pair of charge is given by
U=1/4π∈₀×(q₁q₂/r)
Hence for a system of three charges the electrostatic potential energy can be found by adding up the potential energy for all possible pairs or charges.For three equal charges on the corners of an equilateral triangle,the electrostatic potential energy is given by:
U=1/4π∈₀×(q²/r)+1/4π∈₀×(q²/r)+1/4π∈₀×(q²/r)
U=3×1/4π∈₀×(q²/r)
Substitute given values
So
Explanation:
It is given that,
Power consumed by toaster oven,
Time taken, t = 6 minutes = 0.1 hour
Energy used by toaster,
Similarly,
Power consumed by toaster oven,
Time taken, t = 9 minutes = 0.15 hour
Energy used by toaster,
Hence, this is the required solution.
