A particle is projected in air at some angle to the horizontal , moves along parabola shown in the figure where x and y indicate horizontal and verticle diections, respectively. Shown in the diagram, direction of velocity and acceleration at point A,B and C.

A mass M of 100 kg is suspended with the use of strings A,B and C as shown in the figure,where W is the vertical wall and R is a rigid horizontal rod.The tension in the sttring B is : .

Two identical plane metallic surfaces A and B are kept parallel to each other in air separated by a distance of 10 cm as shown in Figure. Surface A is given a positive Potential of 10 V and outer surface of B is earthed. What is the magnitude and directions of uniform electric field between points Y and Z?

In the figure gives a speed-time graph of a particle in motion along a constant direction. Three equal intervals of time are shwon. In which interval is the average acceleration greatest in magnitude ? In which interval is the average speed greatest ? Choosing the positive direction as the constant direction of motion, give the signs of v and a in the three intervals. What are the acceleration at the points A,B,C and D?

An electron moves along x direction. It enters into a region of uniform magnetic field B directed along -z direction as shown in the figure. Draw the shape of trajectory followed by the electron after entering the field.

If a particle of charge q is moving with velocity v along x-axis and the magnetic field B is acting along Y-axis, use the expression vecF=q(vecv xx vecB) to find the direction of force vecF acting on it.

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?

A uniform electric field of strength 2xx10^3NC^-1 is established between two parallel plates of length 0.1 m held horizontally at a distance 0.02 m apart. An electron is projected at a speed of 6xx10^6 ms^-1 making an angle 45^@ as shown in the figure The field is directed vertically upwards. Will the electron strike the either plate? If it strikes the plate, where does it do so?

A man leaves his home early in the morning to have a walk. He arrives at a junction of roads A and B as shown in figure. He takes the following steps in later journies : (i) 1 km in North direction. (ii) Changes direction and moves in North-East direction for 2 sqrt(2) km. (iii) Changes direction and moves Southwards for distance of 2 km. (iv) Finally he changes the direction and moves in South-East direction to reach road A again. Now if roads A and B are taken as X-axis and y-axis ,then visible point representing the graph of y=f(x) Then the value of x at which function f(x) is discontinous
