Question

A point charge q₁ = -8.9 μC is located at the center of a thick conducting shell of inner radius a = 2.7 cm and outer radius b = 4.9 cm, The conducting shell has a net charge of q₂ = 1.9 μC.

a) What is Eₓ(P), the value of the x-component of the electric field at point P, located a distance 6.7 cm along the x-axis from q₁?

Answer 1

The torque produced by the two masses mounted on a spindle can be calculated using the equation: Torque = force x lever arm. By substituting the values of the masses and their distances from the axis of rotation, we can find the magnitude of the resultant torque.

The torque produced by a force acting on a lever arm is given by the equation:

Torque = force x lever arm

In this case, we have two masses mounted on a spindle that can rotate about the x-axis. To find the magnitude of the resultant torque, we need to know the distance of each mass from the axis of rotation. Let's call the distance of the 7.00 kg mass 'd1' and the distance of the 4.00 kg mass 'd2'.

The total torque can then be calculated as:

Total torque = (7.00 kg x d1) + (4.00 kg x d2)

Make sure to substitute the correct values for 'd1' and 'd2' to find the final answer.
