Because there is no record of all things. As we have partially unknow information, it can never be held as a fact.
Its rays point away from the charge
Answer:
The magnitude and direction of the resultant force are approximately 599.923 newtons and 36.405°.
Explanation:
First, we must calculate the resultant force (
), in newtons, by vectorial sum:
(1)
Second, we calculate the magnitude of the resultant force by Pythagorean Theorem:


Let suppose that direction of the resultant force is an standard angle. According to (1), the resultant force is set in the first quadrant:

Where
is the direction of the resultant force, in sexagesimal degrees.

The magnitude and direction of the resultant force are approximately 599.923 newtons and 36.405°.

Answer:
Moment of the force is 20 N-m.
Explanation:
Given:
Force exerted by the person is, 
Distance of application of force from the point about which moment is needed is, 
Now, we know that, moment of a force 'F' about a point at a perpendicular distance of 'd' from the same point is given as the product of the force and the perpendicular distance.
Therefore, the moment of the force about the end of the claw hammer is given as:

Hence, the moment of the force exerted by the person about the end of the claw hammer is 20 N-m.
