Q1. 6.4 MHz expressed in Hz is:

  1. 6.4 × 10⁷ Hz
  2. 6.4 × 10⁻⁶ Hz
  3. 6.4 × 10⁶ Hz
  4. 6.4 × 10⁵ Hz
Show the answer

Answer: C. 6.4 × 10⁶ Hz

1 MHz = 10⁶ Hz, so 6.4 MHz = 6.4 × 10⁶ Hz.

Q2. A vector has components Ax = 1 and Ay = 1. The angle it makes with the x-axis is:

  1. 30°
  2. 90°
  3. 55°
  4. 45°
Show the answer

Answer: D. 45°

The correct answer is “45°”. tan θ = Ay/Ax = 1/1 → θ = 45°.

Q3. A 0.5 kg mass rotates at 5 rad/s in a circle of radius 0.5 m. The centripetal acceleration is:

  1. 6.25 m/s²
  2. 12.5 m/s²
  3. 25 m/s²
  4. 2.5 m/s²
Show the answer

Answer: B. 12.5 m/s²

The correct answer is “12.5 m/s²”. a = rω² = 0.5 × 5² = 12.5 m/s².

Q4. The speed of a car is increased from v to 2v. Its kinetic energy increases by a factor of:

  1. 3
  2. 2
  3. 4
  4. 8
Show the answer

Answer: C. 4

The correct answer is “4”. KE ∝ v², so the factor is 2² = 4.

Q5. A spring is extended by 1 cm by a force of 100 N (within its elastic limit). Its force constant is:

  1. 10000 N/m
  2. 100 N/m
  3. 1 × 10⁶ N/m
  4. 1 N/m
Show the answer

Answer: A. 10000 N/m

The correct answer is “10000 N/m”. k = F/x = 100/0.01 = 10000 N/m.

Q6. The number of molecules in 3 mol of a gas is:

  1. 1.81 × 10²⁴
  2. 4.98 × 10⁻²⁴
  3. 1.81 × 10²⁵
  4. 1.81 × 10²³
Show the answer

Answer: A. 1.81 × 10²⁴

The correct answer is “1.81 × 10²⁴”. N = nN_A = 3 × 6.02×10²³ = 1.81 × 10²⁴.
