A body is left from the point A and allowed to ovig along the path ABCD which is smooth. The thin arrow represents velocity and the thick arrow represents acceleration. What is wrong with one of the arrow?

Rita goes 20 km towards east from a point A to the point B. From B, she moves 30 km towards west along the same road. If the distance towards east is represented by a positibe integer then, how will you represent the distance travelled towards west? By which integer will you represent her final position from A?

A circular cycle track has a circumference of 314 m with AB as one of its diameter.s A cyclist travels form A to B along the circular path with a velocity of constant magnitude 15.7 m/s. Find the displacement of the cyclist of AB represents north -south direction, with A towards North and B towards south.

A cyclist starats from centre O of a circular park of radius 1 km and moves along the path OPRQO as shown in the figure.If he maintains constant speed of 10 ms^(-1) , what is his acceleration at point R in magnitude and direction?

Answer the following questions: A magnetic field that varies in magnitude from point to point but has a constant direction (east to west) is set up in a chamber. A charged particle enters the chamber and travels undeflected along a straight path with constant speed. What can you say about the initial velocity of the particle?

A body of mass m is attached to one end of a massless spring which is suspended vertically from a fixed point. The mass is held in hand so that the spring is neither stretched nor compressed. Suddenly the support of the hand is removed. The lowest position attained by the mass during oscillation is 4 cm below the point, where it held in hand. What is the amplitude of oscillation?

A test charge q is moved without acceleration from A to C along the path from the point A to B and then from B to C in electric field as shown in fig. At which point( of the two) is the electric potential more and why?

Which of the following examples represent (nearly) simple harmonic motion and which represent periodic but not simple harmonic motion? motion of a ball bearing inside a smooth curved bowl, when released from a point slightly above the lower most point

One method of prodocing two in - phase point sources of light for interference is to form two images of a point source by means of the two halves of a lens,which has been split along a diameter[Fig.6.17]. A screen placed perpendicular tot he principal axis and 80 cm from the mage sources.What is the width of central maxima formed on the screen,if the wavelength of the light used is 5.4 xx 10^(-5) cm ?
