11th-jee

A toy car with charge q moves on a frictionless horizontal plane surface under the influence of a uniform electric field Ē. Due to the force qĒ, 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 1300 average speed of the toy car between 0 to 3 seconds are respectively

11th-jee

Preeti reached the metro station and found that the escalator was not working. She walked up the stationary escalator in time t1. On other days, if she remains stationary on the moving escalator, then the escalator takes her up in time t2. The time taken by her to walk up on the moving escalator will be

11th-jee

A body starts from rest. What is the ratio of the distance travelled by the body during the 4th and 3rd second?

11th-jee

For a particle executing S.H.M. the displacement x is given by x = A cos wt. Identify the graph which represents the variation of potential energy (P.E) as a function of time t and displacement x

11th-jee

Starting from the origin a body oscillates simple harmonically with a period of 2s. After what time will its kinetic energy be 75% of the total energy

11th-jee

If x, v and a denote the displacement, the velocity and the acceleration of a particle executing simple harmonic motion of time period T, then which of the following does not change with time

11th-jee

The x-t graph of a particle undergoing simple harmonic motion is shown below. The acceleration of the particle at t = 4/3 s is

11th-jee

A particle executing simple harmonic motion of amplitude 5 cm has maximum speed of 31.4 cm/s. The frequency of its oscillation is

11th-jee

point mass is subjected to two simultaneous sinusoidal displacements in x-direction, x1( t ) = A sin ωt and x2(t)=Asin(ωt+2π3/). Adding a third sinusoidal displacement x3(t)=Bsin(ωt+ϕ) brings the mass to a complete rest. The values of B and ϕ are

11th-jee

Two particles are executing simple harmonic motion of the same amplitude A and frequency w along the x-axis. Their mean position is separated by distance X0(X0>A). If the maximum separation between them is (X0 + A) the phase difference between their motion is
