Electrostatics – One mark and two marks questions for practice

So far we were concentrating on 3 and five marks questions only. Now I think that concentrating on one and two marks questions will further increase the chance of scoring better.

It’s true that just by concentrating on the three marks and five marks questions one can easily score greater than 60% marks. But it is not enough. When you CAN SCORE MORE why should you compromise for less?

Often the one and two marks questions are tricky and twisted. But, when the questions are tricky, there is a greater chance to score. All you need is to apply your commonsense (often complained that it is not so common!) and logical reasoning. The basic facts remain the same however the question maker twist them. So, believe that whatever question asked are based on what you have learnt. But beware!, whatever conclusions you draw must satisfy your commonsense as well as that of the examiner.

So, here are a collection of one mark and two marks questions from ELECTROSTATICS. The straight – forward questions are intentionally avoided.

Numericals from Kinematics

PHYSICS TEST (CLASS XI) Kinematics

  1. A particle is projected at 60º to the horizontal with a kinetic energy K. What is the kinetic energy at the highest point
  2. Which of the following statements is false for a particle moving in a circle with a constant angular speed?
    (a) the velocity vector is tangent to the circle
    (b) the acceleration vector is tangent to the circle
    (c) the acceleration vector points to the centre of the circle
    (d) the velocity and acceleration vectors are perpendicular to each other
  3. A car is moving in a circular horizontal track of radius 10.0 m with a constant speed of 10.0m/s.A plumb bomb is suspended from the roof of the car by a light rigid rod of length1.00m. What is the angle made by the rod with the track is (g= 10 m/s²)
  4. The distance traveled by an object along the axes are given by x=2t², y = t² – 4, z = 3 t – 5. What is the initial velocity of the particle
  5. A boy playing o the roof of 10m high building throws a ball with a speed of 10 m/s at an angle of 30º the horizontal. How far from the throwing point will the ball be at the height of 10m from the ground?
  6. If a body travels half of its path in the last second of its fall from rest; find the time and height of its fall?
  7. An object A is kept fixed at the point x = 3m and y=1.25m on a moving along the +x direction with an acceleration 1.5 m/s. At the same instant a stone hitting the object during its downward motion at an angle pf 45º to the horizontal .all the motions are in X-Y plane .Find u and time after which stone hits the object. Take g = 10m/s²
  8. Three particles a, b and c are situated at the vertices of an equilateral triangle ABC of side d at t=0. Each of the particles moves with constant speed v. A always has its velocity along BC and C along CA. At what time will the particles meet each other?
  9. A man standing on road has to hold his umbrella at 30º with the vertical to keep the rain away he throws the umbrella and starts running at 10 km/h. he finds that  raindrops with respect to [a]the road, [b] the moving man.
