Answer:
the answers for the first 3 are
C
A
C
Explanation:
Answer:
One should draw a diagram showing the placement of the charges.
When both charges of -Q are placed there will be no force in the vertical direction because of cancellation of forces.
A line from one corner of the square to the other makes an angle of 45 degrees,
2 cos 45 deg will be the force due to one charge.
2 * .707 = 1.41 N
So for both charges the force is (horizontal, vertical is zero)
2 * 1.41 = 2.82 N
b) is correct
You would know it must have a charge, an Ion is a positively charged or negatively charged atom, so if it's an ion you know it has to have a charge.
Explanation:
volume=3x4x6=72cm³
density=mass/volume
so:
