Find CBSE Class 12 Physics Practice Paper (Set-I). This paper contains important questions from 1st unit (Electrostatic) of physics. These questions will not only help the students to prepare for exams in a better manner, but will also help them in understanding the depth with which a topic should be studied.
Few sample questions from the Question Paper are given below:
Q. On what factors does the capacitance of a cpacitor depend?
Q. Write a relation for polarisation of a dielectric material in the presence of an external electric field.
Q. What is principal of superposition? Also write an expression for net force on test charge qo due to q1, q2, q3, q4......qn.
Q. Two point charges of 16 C and -9 C are placed 8 m apart in air. Determine the position of the point at which the resultant electric field is zero?
Q. When a glass rod is rubbed with a silk cloth, charges appear on both objects. A similar phenomenon is observed with many other pairs of bodies. Explain how this observation is consistent with the law of conservation of charge.
