The magnitude of the electrostatic force between two charges is given by:

where
ke is the Coulomb's constant
q1 and q2 are the two charges
r is the separation between the two charges
We can see that the magnitude of the force is directly proportional to the charges. This means that when one of the charges is doubled, the magnitude of the electrostatic force will double as well, so the correct answer is
A) <span>The magnitude of the electrostatic force doubles</span>
Answer:
g = 11.2 m/s²
Explanation:
First, we will calculate the time period of the pendulum:

where,
T = Time period = ?
t = time taken = 135 s
n = no. of swings in given time = 98
Therefore,

T = 1.38 s
Now, we utilize the second formula for the time period of the simple pendulum, given as follows:

where,
l = length of pendulum = 54 cm = 0.54 m
g = acceleration due to gravity on the planet = ?
Therefore,

<u>g = 11.2 m/s²</u>

No, you would aim slightly above, because when you throw the spear and it travels through the air it will fall slightly downwards by the time it reaches the fish.
Answer:
The magnitude of Resultant force is F = 7.21-lbs
Explanation:
Two forces acting on an object which are named as F1 and F2.
The angle formed by the forces are 60-degrees
F1 = 6-lbs , F2 = 8-lbs
theeta = 60°
F = √F1²+F2²-2(F1)(F2)cos(theeta)
F = √(6)²+(8)²-2(6)(8)cos(60)
F = √36+64-(96)cos(60)
F = 7.21-lbs
where,
F1 = magnitude of force 1
F2 = magnitude of force 2
theeta = angle formed by forces
