JEE

The common mistakes can be - using the formula incorrectly, before applying the formula students not simplify the expression, in Binomial Expansion, sometimes they forget to include the fractional and negative exponents, and using incorrect values for a, b, and n.

The Binomial model is known as the Lattice Model or Binomial Option Pricing Model.

There are a total of 36 questions comprising 14 straightforward formula-based sums, 16 challenging problems, and 6 intermediate.

Mathematically, binomial theorem formula is: (a + b)n = nC0 an + nC1 an - 1b + nC2 a n – 2b 2 + . + nCn – 1a.bn - 1 + nCn bn. Here a and b are real numbers and n is a positive integer.

An expression with two terms raised to a positive integer power can be expanded in Maths, such as (a + b)? This algebraic rule is known as the Binomial Theorem. 

Usually, there are 3–4 rounds of NCHMCT JEE counselling, followed by a spot round if seats remain vacant.

Yes, SNU does accept JEE Main scores for admission to its BTech course. The accepted entrance exams for BTech is only JEE Main. Hence, students must prepare well for the JEE Main in advance. For other details, please visit the official website of the university and apply for admission to various courses. 

In JEE Main exam, it is a significant chapter. There can be 6 to 8 questions from this chapter, a weightage of nearly 6.6%.

The exact weightage varies from year to year. This chapter comes under a broader category which can be "Magnetism" or "Modern Physics". In NEET exam, the chapter's weightage is low to moderate and there can be 6-7% of questions from this chapter.

The chapter is one of the small and easy chapter of class 12 Physics. It includes - properties of magnetic materials, magnetic dipoles, and Earth's magnetic field.
