Q. The force on a charged particle moving in a magnetic field is given by which law? (2021)
A.
Coulomb's Law
B.
Lorentz Force Law
C.
Faraday's Law
D.
Ampere's Law
Solution
The force (F) on a charged particle moving in a magnetic field is described by the Lorentz Force Law, F = q(v × B), where q is the charge, v is the velocity, and B is the magnetic field.
Q. The frequency of a wave is 10 Hz. What is the frequency of its second harmonic? (2021)
A.
5 Hz
B.
10 Hz
C.
20 Hz
D.
30 Hz
Solution
The frequency of the second harmonic is twice the fundamental frequency. Therefore, if the fundamental frequency is 10 Hz, the second harmonic frequency is 2 * 10 Hz = 20 Hz.
Q. The Freundlich adsorption isotherm is best described by which equation? (2023)
A.
x/m = kP
B.
x/m = kP^(1/n)
C.
P = k(x/m)
D.
P = k(x/m)^(1/n)
Solution
The Freundlich isotherm is represented by the equation x/m = kP^(1/n), where x is the amount adsorbed, m is the mass of the adsorbent, and P is the pressure.
Q. The half-life of a first-order reaction is independent of the initial concentration of the reactant. What is the expression for the half-life (t1/2) of a first-order reaction? (2020)
A.
t1/2 = 0.693/k
B.
t1/2 = k/0.693
C.
t1/2 = 1/k
D.
t1/2 = k/1
Solution
The half-life of a first-order reaction is given by the formula t1/2 = 0.693/k, which shows that it is independent of the initial concentration.
Q. The half-life of a first-order reaction is independent of the initial concentration of the reactant. What is the expression for the half-life (t₁/₂)? (2022)
A.
t₁/₂ = 0.693/k
B.
t₁/₂ = k/0.693
C.
t₁/₂ = 1/k
D.
t₁/₂ = k/1
Solution
The half-life of a first-order reaction is given by t₁/₂ = 0.693/k.
Q. The half-life of a first-order reaction is independent of the initial concentration of the reactant. What is the expression for the half-life? (2022)

C.
t₁/₂ = 1/k
D.
t₁/₂ = k/1
Solution
The half-life of a first-order reaction is given by t₁/₂ = 0.693/k.
