Q) What is the acceleration due to gravity on the surface of the Earth?
(A) 9.8 m/s
(B) 9.8 m/s²
(C) 9.8 km/s²
(D) 9.8 cm/s²
Correct Answer - Option
(B)
Explanation :
The acceleration due to gravity near the Earth's surface is approximately 9.8 m/s².
Q) Which law states that current is directly proportional to voltage and inversely proportional to resistance?
(A) Newton's Law
(B) Coulomb's Law
(C) Ohm's Law
(D) Faraday's Law
Correct Answer - Option
(C)
Explanation :
Ohm’s Law states that V = IR, where current (I) is directly proportional to voltage (V) and inversely proportional to resistance (R).
Q) What is the unit of power?
(A) Joule
(B) Watt
(C) Newton
(D) Coulomb
Correct Answer - Option
(B)
Explanation :
Power is the rate at which work is done, measured in watts (1 watt = 1 joule/second).
Q) Which physical quantity is measured in Pascal?
(A) Force
(B) Pressure
(C) Energy
(D) Power
Correct Answer - Option
(B)
Explanation :
Pressure is measured in pascals (Pa), where 1 Pa = 1 N/m².
Q) What happens to the frequency of a wave if its wavelength decreases and speed remains constant?
(A) It increases
(B) It decreases
(C) It remains constant
(D) It becomes zero
Correct Answer - Option
(A)
Explanation :
Since wave speed = frequency × wavelength, a decrease in wavelength means frequency must increase if speed is constant.
Q) Which of the following is a non-renewable source of energy?
(A) Solar energy
(B) Wind energy
(C) Coal
(D) Hydroelectric power
Correct Answer - Option
(C)
Explanation :

(A) Convex mirror
(B) Concave mirror
(C) Plane mirror
(D) Parabolic mirror
Correct Answer - Option
(B)
Explanation :
Concave mirrors are used in headlights because they converge light rays into a strong, parallel beam.
Q) What type of lens is used to correct myopia (short-sightedness)?
(A) Convex lens
(B) Concave lens
(C) Cylindrical lens
(D) Plano-convex lens
Correct Answer - Option
(B)
Explanation :
A concave lens diverges light rays, helping the image form correctly on the retina for people with myopia.
Q) Which of the following is not a scalar quantity?
(A) Mass
(B) Velocity
(C) Temperature
(D) Energy
Correct Answer - Option
(B)
Explanation :
Velocity is a vector quantity because it has both magnitude and direction.
Q) Which instrument is used to measure electric current?
(A) Voltmeter
(B) Ammeter
(C) Galvanometer
(D) Ohmmeter
Correct Answer - Option
