Physics is the science of matter and motion. Given below are the 5 practical oriented basic physics MCQs with their answers.
In certain experimental setting air-friction is made zero. A feather and a hammer is dropped from the same certain height. Which of following statement is correct:
- Feather will reach ground first
- Hammer will reach first on ground
- Both will reach at same time
- Both will stay in air
Correct answer: 3. Both will reach at same time
Without air resistance all objects fall at same speed
Cyan + Magenta + Yellow =
- White
- Black
- Blue

Jack is passing near a well while a coin accidently slips and drops in well. The sound of coin is heard after 1 second. The depth of well is:
- 4.9 m
- 9.8 m
- 19.6 m
- Can’t predict from given data
Correct answer: 1. 4.9 m
The resistance of a 180 m long Tungsten wire having cross-section area 0.3 mm2 is:
- 1.56*10-05
- 2.88*10-05
- 3.29*10-05
- 4.54*10-05
Correct answer: 3. 3.29*10-05
Solution: R = ( ρ.l)/a = (5.60*10-8. 180 m) / 0.3 mm2 = 3.29 *10-05
