Hace 3 días · Hence, the average force on each electron is \[5 \times {10^{ - 25}}\;{\text{N}}\]. The correct option is A. Note: In order to calculate the average force we use the formula for magnetic force which is given by, \[F = Be{v_d}\]. Where, \[{v_d}\] is drift velocity of electrons and the formula for drift velocity is given by, \[{v_d} = \dfrac{I ...
Hace 5 días · Thus, the net force will be zero. Hence, the correct answer is option (C) zero. Note: Force acting on a conductor with closed loop due to a uniform magnetic field acting perpendicular to the loop is always zero. However if the magnetic field is changing with time or it is not a closed loop, then there will be some net force acting on the conductor.
Hace 3 días · Hint: We know that Lenz’s law is used to find the direction of the induced current due to the varying magnetic field. Here since the current in the coil is varying, this produces an induced current in the rod. Then we can find the force on the ring. Complete step by step answer: Consider the direction of current as shown in the diagram.

Hace 4 días · Hint: A force is said to be conserved if the work done by the force in moving a particle form one point to another point depends totally only on the initial and final points. The force acting on the particle doesn’t depend on the path followed. Complete step by step answer: Let us first assume two points a and b in an electric field due to ...
Hace 3 días · Here, E represents the electric field force, q is the charge of the electron, m is the weight of the oil drop and g represents the gravity. Given that there are 12 excess electrons, so the charge q will be 12 times the charge of one electron.
