Answer:
a) 9.0
Explanation:
The force between two point charges, obeys Coulomb's Law, which can be written as follows:
As it can be seen, if the separation between the charges remains the same, the new value of the force will be directly proportional to the product of the charges.
If both charges are tripled, the mutual force between them will be changed in a factor equal to 3.0*3.0 = 9.0
Explanation:
Remember Newton's Second Law.
If the force acting on both bikers is the same, we can look at the relationship between acceleration and mass.
If Biker 1 has a mass of 10kg and Biker 2 has a mass of 20kg, and both are being acted upon by a force of 100 N, let's see what that looks like.
So, given the same force, an object with GREATER mass will have less acceleration.
