Sample Questions

Q1Section 1 – Single Correct

A particle of mass ݉ is initially at rest at the origin. It is subjected to a force and starts moving along the ݔ-axis. Its kinetic energy ܭ changes with time as ݀ܭ/݀ݐ ൌߛݐ, where ߛ is a positive constant of appropriate dimensions. Which of the following statements is (are) true?

A.The force applied on the particle is constant
B.The speed of the particle is proportional to time
C.The distance of the particle from the origin increases linearly with time
D.The force is conservative
Q2Section 1 – Single Correct

Consider a thin square plate floating on a viscous liquid in a large tank. The height ݄ of the liquid in the tank is much less than the width of the tank. The floating plate is pulled horizontally with a constant velocity ݑ଴. Which of the following statements is (are) true?

A.The resistive force of liquid on the plate is inversely proportional to ݄
B.The resistive force of liquid on the plate is independent of the area of the plate
C.The tangential (shear) stress on the floor of the tank increases with ݑ଴
D.The tangential (shear) stress on the plate varies linearly with the viscosity ߟ of the liquid
Q3Section 1 – Single Correct

An infinitely long thin non-conducting wire is parallel to the ݖ-axis and carries a uniform line charge density ߣ. It pierces a thin non-conducting spherical shell of radius ܴ in such a way that the arc ܲܳ subtends an angle 120° at the centre ܱ of the spherical shell, as shown in the figure. The permittivity of free space is ߳଴. Which of the following statements is (are) true?

A.The electric flux through the shell is √3ܴߣ/߳଴
B.The ݖ-component of the electric field is zero at all the points on the surface of the shell
C.The electric flux through the shell is √2ܴߣ/߳଴
D.The electric field is normal to the surface of the shell at all points
