Assertion(A). The strength of the magnetic
field produced at the centre of a current
carrying circular coil increases on
increasing the number of turns of
the circular coil.
Reason(R) - Magnetic field strength is directly proportional to the number of turns of the circular coil.
1- Both A and R are true and R is correct explanation of A.
2- Both A and R are true and R is not correct explanation of A
3- A is true but R is false
4- A is false but R is true

What is the standard form of a rational number?
A rational number
a
b
is said to be in the standard form if b is positive, and the integers a and b have no common divisor other than 1.
How to convert a rational number into standard form?
In order to express a given rational number in the standard form, we follow the following steps:
Step I: Obtain the rational number.
Step II: See whether the denominator of the rational number is positive or not. If it is negative, multiply or divide numerator and denominator both by -1 so that denominator becomes positive.
Step III: Find the greatest common divisor (GCD) of the absolute values of the numerator and the denominator.
Step IV: Divide the numerator and denominator of the given rational number by the GCD (HCF) obtained in step III. The rational number so obtained is the standard form of the given rational number.
