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

The strength of each of magnet reduces to half when it cut along its length into the equal parts magnetic field strength of a solenoid. Polarity of solenoid can be determined by:

4 / 25

When current is parallel to magnetic field, then force experience by the current carrying conductor placed in uniform magnetic field is

5 / 25

The instrument that use to direct electric current in the circuit is known as:

6 / 25

The magnetic feld inside a long straight solenoid carrying current is

7 / 25

A device that can convert electrical energy into mechanical energy is

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

9 / 25

The resistance of hot filament of the bulb is about 10 times the cold resistance. What will be the resistance of 100 W-220 V lamp, when not in use?

10 / 25

A cell, a resistor, a key, and an ammeter are arranged as shown in the circuit diagrams. The current recorded in the ammeter will be:

11 / 25

Copper is not approved to make fuse wire because it:
