Three objects lie in the x, y plane. Each rotates about the z axis with an angular speed of 5.58 rad/s. The mass m of each objec
t and its perpendicular distance r from the z axis are as follows: (1) m1 = 5.46 kg and r1 = 1.98 m, (2) m2 = 3.64 kg and r2 = 16.50 m, (3) m3 = 3.21 kg and r3 = 3.09 m. (a) Find the tangential speed of each object.
(b) Determine the total kinetic energy of this system using the expression KE =
The magnetic force on a charged particle is given as: F = qvBsinФ B is the magnetic field. q is the charge on the particle. v is the velocity of the charged particle. Ф is the angle between magnetic field (B) & the velocity of charge (v).
⇒ F = qvb sin Ф
Here, Ф = 90 degree. and sin 90 = 1 Putting the values in the equation, we get,
F = 1.6 x 10^-19 C × 4.5 × 10^7 m/s × 1.6 T = 11.52 × 10^-12N = 1.2 x 10^-11 N up
