Hi there!
We can use the following equation for a point charge in a magnetic field:
= Force due to magnetic field (7.6 × 10⁻¹³N)
= Charge of particle (1.6 × 10⁻¹⁹ C)
= velocity of particle (6.6 × 10⁶ m/s)
= Magnetic field strength (1.8 T)
Or, without the cross product:
θ = angle between particle's velocity and field
We can rearrange to solve for theta:
Solve for theta:
Explanation:
(a) The given data is as follows.
Length of the rod, L = 0.83 m
Mass of the rod, m = 110 g = 0.11 (as 1 kg = 1000 g)
At the lowest point, angular speed of the rod () = 5.71 rad/s
First, we will calculate the rotational inertia of the rod about an axis passing through its fixed end is as follows.
I =
=
=
= 0.00631 + 0.415
= 0.42131
Therefore, kinetic energy of the rod at its lowest point will be calculated as follows.
K =
=
= 6.86 J
Hence, kinetic energy of the rod at its lowest point is 6.86 J.
(b) According to the conservation of total mechanical energy of the rod, we have
or, mgh = K = 6.86 J
Therefore, h =
=
= 0.584 m
Hence, the center of mass rises 0.584 m far above that position.
