A particle has a velocity u towards east at t = 0. Its acceleration is towards west and is constant.

Since the positively charged particle (alpha-particle) projected towards west, so the direction of current is towards west. Now the deflection is towards north, so the force is towards north' Now...

(d) the information is insufficient to decide the relation of xA with xB. Explanation: Magnitude of displacement depends up on initial velocity, time Duration and acceleration. In this case only time is known while magnitude of initial velocity and acceleration...

(d) > 500N for time Δt1 and Δt3 and 500N for Δt2. Explanation:  During the constant velocity for time Δt2 there is no relative movement between the man and the seat and only force applied by the seat on...

The correct answer is (a) F1 > F2.  Explanation: The earth spins from west to east at equator. To maintain the same speed the first train has to press the track more than normal as...

(d) downward.

(b) gradually decrease

(d) its velocity and acceleration both change. Explanation: Velocity and acceleration are both vectors and a vectors is fully defined with its magnitude and direction. Even when one entity changes, the vector...

The correct answer is (a) F1 > F2.  Explanation: The earth spins from west to east at equator. To maintain the same speed the first train has to press the track more than normal...

(a) Bay of Bengal is the largest bay in the world. It finds a triangle in a shape and its bordered mostly by the eastern coast of India, Southern west...

(D) North-East
