Answer:
F = + 6 [N] That is, this force points to the right
Explanation:
We have two forces, one of them pointing to the left with a value of 2 [N] while the other Force points to the right with a value of 8 [N].
In this way performing an arithmetic operation we can find the resulting force.
F = -2 + 8
F = + 6 [N]
That is, this force points to the right
I'd say ground. <span>Voltage in the US is 110-120 volts while in other countries it is 220-240 volts. if you have a 110-120 volt appliance, you need a step-up transformer (110 to 220)before you could use it in a 220 volt power supply.</span>
