2 cylinders P and Q of equal mass are made from same metal if the radius of P is n times the radius of Q then , calculate the ratio of their resistance.
please write full solution and correct answer.
Answers
Two solid cylinders P and Q of same mass and same radius start rolling down a fixed inclined plane from the same height at the same time. Cylinder P has most of its mass concentrated near its surface, while Q has most its mass concentrated near the axis. Both cylinders P and Q reach the ground at the same time.
Cylinders P has larger linear acceleration than cylinder Q.
Both cylinders reach the ground with same translational kinetic energy.
Cylinder Q reaches the ground with larger angular speed
Explanation:
A cylinder is a three-dimensional solid that holds two parallel bases joined by a curved surface, at a fixed distance. These bases are normally circular in shape and the center of the two bases are joined by a line segment, which is called as the axis.
