CBSE Class X – Science Physics Exam (Full Syllabus)

This test is designed based on NCERT Syllabus for Class 10 Topics of Science – Physics

Each time random 25 questions will be displaced from the question bank of 500 + Questions
So we recommend you to retake the quiz till you have mastered all the questions

1 / 25

Inside the magnet, the field lines move from :

from south to north

from north to south

away from north pole

away from south poles

2 / 25

For a current in a long straight solenoid N and S-poles are created at the two ends. Among the subsequent declaration , the incorrect declaration is:

The feld lines inside the solenoid are in the form of straight lines, which indicates that the magnetic field is the same at all points inside the solenoid

The strong magnetic feld produced inside the solenoid can be used to magnetise a piece of magnetic material like soft iron, when placed inside the coil

The pattern of the magnetic feld associated with the solenoid is diferent from the pattern of the magnetic field around a bar magnet

The N and S-poles exchange position when the direction of current through the solenoid is reversed

8 / 25

You are holding the current-carrying wire in your right hand so that your thumb points in the direction of current, then the direction in which your fingers encircle the wire will give the direction of the magnetic feld lines around the wire.explain

18 / 25

A clear sky appears blue, because:

blue light gets absorbed in the atmosphere

ultraviolet radiations are absorbed in the atmosphere

violet and blue lights get scattered more than the lights of all other colours by the atmosphere

lights of all other colours is scattered more than the violet and blue colour lights by the atmosphere

19 / 25

The red colour of the sun at the time of sunrise and sunset is because:

red colour is least scattered

blue colour is least scattered

red colour is most scattered

blue colour is most scattered

20 / 25
