Answer: c)• 2/3
Explanation:
Lets say q1 and q2 are two charges with r distance far apart.
So electrostatic force
F = (k q1 q2) / r²
as k = Coulomb's constant
Now
q1' = 2q1
q2' = q2/3
Therefore the new electrostatic force
F' = (k q'1 q'2) / r²
F' = (k 2q1 q2) / 3r²
F' = 2/3 [(k q1 q2) / r²]
so F' = 2/3F
New electrostatic force is 2/3F
Answer:
Gravity. the weight force or weight of an object is the force because of gravity which acts on the object attracting it towards the center of the earth mass is a measure of the amount of material or matter that an object contains
Answer:
Tension must a rope be stretched is 36.8828 N
Explanation:
Wave speed in term of wavelength:
Where:
f is the frequency
is the wavelength
Now:
Wave speed in term of tension force and mass per unit length
Eq (1)
Where:
F is the tension force
Since 
is calculated above.On rearranging Eq (1) we will get:
Tension must a rope be stretched is 36.8828 N
answer
6000 N
explanation
every force has an equal and opposite reaction force, so the force exerted by the truck on the car is the same as the force exerted by the car on truck
the force is 6000 N
