Given that the potential difference is V = 1.5 V.
The length of the wire is l = 1.5 m.
The cross-sectional area is
The resistivity of the wire is
We have to find the power dissipated in the wire.
First, we need to calculate resistance.
The resistance can be calculated as
The formula to calculate power is
Substituting the values, the power will be
Thus, the power dissipated in the wire is 17.1 W
The electrostatic force between two bodies is proportional to the product of their two charges. If the charge on A is increased this product increases in size (it must have been non-zero to begin with, since there was a force between them at first). Thus, the force between them rises.
Answer:
D
Explanation
take 5x2000 and J is the unit for power therfore it cant be A and B and C are not 10,000.
