Question 2 (2 points)
In which direction is there a net force of 200 N?
300 N
200 N
400 N
300 N

right

Explanation: Because up and down both have the same amount of force they end up cancelling each other out (300N - 300N = 0N)

Now the obv stronger net force between left and right is right so (400N - 200N = 200N) so right cancels out left leaving the right side with 200N.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
