Use the right hand dynamo rule to predict which way the induced current flows through the conductor AB in diagrams (a) and (b) below (i) Diagram (a): Magnet stationary, conductor moves in the direction of the arrow. Induced current flows from (ii) Diagram (a): Magnet moves in the direction of the arrow, conductor stationary. Induced current flows from (iii) Diagram (b): Magnet stationary, conductor moves in the direction of the arrow. Induced current flows from (iv) Diagram (b): Magnet moves in the direction of the arrow, conductor stationary. Induced current flows from

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
