If an object moves with speed of light its mass will be.
Correct answer: C. Infinity
- A. Zero
- B. Maximum
- C. Infinity
- D. Minimum
Explanation
The formula that relates an object's mass ( m ) to its velocity ( v ) as it approaches the speed of light ( c ) is given by the relativistic mass formula:m= mo / √ 1−v2 / c2 Here, ( m0 ) is the rest mass of the object, which is the mass measured when the object is at rest relative to the observer.As the velocity ( v ) of the object approaches the speed of light ( c ), the denominator of the Lorentz factor approaches zero, causing the relativistic mass ( m ) to approach infinity.

About Quantum Theory and Radiation
Quantum theory treats electromagnetic radiation as packets of energy called photons, with energy proportional to frequency through E equals hf. The topic covers Planck's hypothesis, photon momentum, the photoelectric effect, threshold frequency, work function and wave particle duality, distinguishing quantised energy exchange from classical continuous radiation.
