Practice these randomly selected questions to test your readiness.
Question 1
A block of mass $m$ is placed on a frictionless surface and connected to a horizontal spring with a force cons\tant $k$. The block is displaced from its equilibrium position by a dis\tance $x$ and released from rest. Assuming the block undergoes simple harmonic motion, what is the maximum speed $v_{max}$ of the block?
Question 2
A 10 V battery is connected to a 2 kΩ resistor in series with a 4 kΩ resistor. Calculate the current in the circuit.
Question 3
A uniform solid sphere of radius $R$ and mass $M$ is floating in a liquid of density $\rho$. The sphere is partially submerged in the liquid, with the volume of the submerged part being $V$. The weight of the sphere is balanced by the buoyant force exerted by the liquid. If the density of the sphere is $sigma$, determine the depth of the center of the sphere below the surface of the liquid.
Question 4
A light ray passes from air into a glass of re\fractive index 1.5. If the angle of incidence is 30°, calculate the angle of re\fraction.
Question 5
A block of mass 5 kg is attached to a horizontal spring with a force cons\tant of 100 N/m. If the block is displaced by 2 m from its equilibrium position and then released, what is the maximum speed of the block?
Question 6
A particle of mass 2 kg is moving in a circular path of radius 3 m with a cons\tant speed of 4 m/s. If the particle is subjected to a magnetic field of 2 T, what is the magnitude of the magnetic force acting on it?
Question 7
A projectile is launched from the ground with an initial velocity of 20 m/s at an angle of 30° above the horizontal. What is the maximum height reached by the projectile?
Question 8
A block of mass 5 kg is attached to a spring with a spring cons\tant of 100 N/m. If the block is displaced by 0.2 m from its equilibrium position, what is the magnitude of the force exerted by the spring?
Question 9
A parallel plate capacitor has a capaci\tance of 10 μF and is charged to a potential difference of 20 V. If the plates are then separated by a dis\tance of 5 cm, what is the new capaci\tance?
Question 10
A 0.50 kg block is attached to a horizontal spring with a force cons\tant of 100 N/m. The block is displaced by 0.10 m from its equilibrium position and released from rest. Calculate the frequency of the block.
Question 11
A gas at 300 K expands from 1.0 L to 2.0 L against a cons\tant external pressure of 1.0 atm. Calculate the work done by the gas.
Question 12
A particle of mass 2 kg is moving in a circular orbit of radius 3 m with a speed of 4 m/s. If the particle is subjected to a uniform magnetic field of 2 T, what is the magnitude of the magnetic force acting on the particle?
Question 13
A capacitor consists of two parallel plates separated by a dis\tance of 2 mm. If the capaci\tance is 10 μF, what is the charge stored on the capacitor when a potential difference of 5 V is applied?
Question 14
A coil of wire with $N$ turns and radius $r$ carries a current $I$. The coil is placed in a uniform magnetic field of strength $B$ directed perp\endicular to the plane of the coil. Determine the torque experienced by the coil.
Question 15
