Answer:
The mass is inversely proportional to the acceleration so the acceleration a1 is twice that acceleration a2
Explanation:
The force of friction and the kinetic force make the law of mass in moving so
The forces are the same however at the moment to determinate the acceleration
are constant because they make the same motion however the difference of mass make the acceleration difference

Answer:
Explanation:
Force of attraction between two charges is 36N
Then from coulombs electrostatic law.
The force of attraction or repulsion between two charges (q1 and q2) is directly proportional to the product of the force and inversely proportional to the square of the distance apart.
F = kq1•q2 / r².
kq1•q2 / r² = 36
Now, we are told that the second charges has increased by a factor of 3
Then,
q2' = 3q2
So, since the first charge is contact, the radius is constant and k is constant,
Then,
F is directly proportional to the second charge, so if the second charge is triple then the force is tripled
Then,
F' = 3F = 3 × 36 = 108 units
Unit of force is newton
F' = 108N
Also,
F' = kq1•q2' / r²
F' = kq1•3q2 / r².
F' = 3 × kq1•q2 / r²
Since, kq1•q2 / r² = 36
Then,
F' = 3 × 36
F' = 108 units
F' = 108N
But the fact is that an accelerating object is an object that is changing it’s velocity.. for this reason , it can be safely concluded that an object moving in a circle at constant speed is indeed accelerating. It is accelerating because the direction of the velocity vector is changing .
