Expert Solution & Answer

Answer to Problem 2FC

The correct optionis (b) East.

Explanation of Solution

Description:

Right-Hand Rule 1 (RHR 1) is stated as when the right hand is extended, the fingers are directed along the direction of the magnetic field, the thumb is directed along the charge velocity, and the palm points at the direction of the magnetic force that acting on the charge.

As per the statement given above, the direction of the magnetic force is in the west. It is to be noted that the given law is for a positively charged particle. However, the given law is for an electron that is negatively charged. Therefore, the direction must be reversed.

Now the direction of the magnetic force is right opposite to the direction of positively charged particle. Hence the new direction will be pointed to the east.

Therefore, option (b) is correct and remaining options (a), (c), (d), and (e)are incorrect.

Conclusion:

Thus, the correct optionis (b) East.

For each of the actions depicted below, a magnet and/or metal loop moves with velocity v→ (v→ is constant and has the same magnitude in all parts). Determine whether a current is induced in the metal loop. If so, indicate the direction of the current in the loop, either clockwise or counterclockwise when seen from the right of the loop. The axis of the magnet is lined up with the center of the loop. For the action depicted in (Figure 5), indicate the direction of the induced current in the loop (clockwise, counterclockwise or zero, when seen from the right of the loop). I know that the current is clockwise, I just dont understand why. Please fully explain why it's clockwise, Thank you

A planar double pendulum consists of two point masses \[m_1 = 1.00~\mathrm{kg}, \qquad m_2 = 1.00~\mathrm{kg}\]connected by massless, rigid rods of lengths \[L_1 = 1.00~\mathrm{m}, \qquad L_2 = 1.20~\mathrm{m}.\]The upper rod is hinged to a fixed pivot; gravity acts vertically downward with\[g = 9.81~\mathrm{m\,s^{-2}}.\]Define the generalized coordinates \(\theta_1,\theta_2\) as the angles each rod makes with thedownward vertical (positive anticlockwise, measured in radians unless stated otherwise).At \(t=0\) the system is released from rest with \[\theta_1(0)=120^{\circ}, \qquad\theta_2(0)=-10^{\circ}, \qquad\dot{\theta}_1(0)=\dot{\theta}_2(0)=0 .\]Using the exact nonlinear equations of motion (no small-angle or planar-pendulumapproximations) and assuming the rods never stretch or slip, determine the angle\(\theta_2\) at the instant\[t = 10.0~\mathrm{s}.\]Give the result in degrees, in the interval \((-180^{\circ},180^{\circ}]\).
