All of the following forces are central force, EXCEPT
Semua yang berikut adalah daya berpusat KECUALI
A)Coulomb force
Daya Coulomb
B) Frictional force
Daya geseran
Friction force, unlike gravitational or electrostatic is not directed toward a source like a center of mass or a charge. Friction is therefore not a central force.
Did you get your earlier one about a = F/m (1- e^(bt/m) )
alright?
I mean
a = (F/m)e^-(bt/m)
To determine which of the forces mentioned are central forces, let's first understand what a central force is. A central force is a force that is always directed towards or away from a fixed point, known as the center.
Let's evaluate each option to see if they are central forces:
A) Coulomb force (Daya Coulomb): The Coulomb force is the force of attraction or repulsion between two charged particles. This force is always directed along the line connecting the two charged particles. Therefore, the Coulomb force is a central force.
B) Frictional force (Daya geseran): The frictional force is a force that opposes the motion or tendency of motion between two surfaces in contact. This force acts parallel to the surfaces and is not directed towards or away from a fixed point. Therefore, the frictional force is NOT a central force.
Based on this evaluation, the correct answer is:
B) Frictional force (Daya geseran)
