Answer:
The new angular velocity will be "80.73 rad/sec".
Explanation:
The given values are:
Angular velocity, W = 20 rad/s
M = 30 N
Time, t = 5 seconds
As we know,
On putting the values in the above formula, we get
Answer:
The magnetic force on a current-carrying wire is perpendicular to both the wire and the magnetic field with direction given by the right hand rule.
Answer:
400 N
Explanation:
Since the steel bar is uniform, its center of mass must be at its geometric center as well, which is at the same spot as the 75kg mass hanging. So the total mass is 75 + 5 = 80 kg.
Suppose g = 10m/s2, we can then calculate the weight of the system:
W = Fg = 80 * 10 = 800 N
As the weight is at the center with 2 ropes supporting on 2 ends, weight should be evenly distributed on each rope. So each rope is subjected to a tension force of
T = 800 / 2 = 400 N
