Question

121. A toy car with charge q moves on a frictionless horizontal plane surface under the influence of a uniform electric field E. Due to the force qE, it's velocity increase from 0 to 6 M/s in one second duration. At that instant the direction of the field is reversed. The car continues to move for two more second under the influence of this field . The average velocity and the average speed of the toy car between 0 to 3 second are respectively.

Q. A toy car with charge q moves on a frictionless horizontal plane surface under the influence of a uniform electric field →E. Due to the force q →E, its velocity increases from 0 to 6 m/s in one second duration. At that instant the direction of the field is reversed. The car continues to move for two more seconds under the influence of this field. The average velocity and the average speed of the toy car between 0 to 3 seconds are respectively

Q. A particle having a charge of 10μC and mass 1μg moves in a horizontal circle of radius 10 cm under the influence of a magnetic field of 0.1 T. When the particle is at a point P, a uniform electric field is switched on so that the particle starts moving along the tangent with uniform velocity. The electric field is.
Q.

A toy-car, blowing its horn, is moving with a steady speed of 5m/s, away from a wall. an observer towards whom the toy car is moving, is able to hear 5 beats per second. If the velocity of sound in air is 340m/s, the frequency of the horn of the toy car is close to:
