Question

At a certain place, the intensity of the magnetic field is 0.2 T and the angle of dip is 60°. What will be the value of the horizontal component (in T)?

• A. 0.2
• B. 0.1
• C. 0.4
• D. 0.3

Answer 1

The correct option is B

0.1

Step 1: Given data

The angle of dip = 60°

The intensity of the magnetic field = 0.2 T

Step 2: Finding the horizontal component of the magnetic field

We know,

$Horizontalcomponent=Intensity\times \cos \alpha$

where $\alpha$= angle of dip

Now putting all the values

$Horizontalcomponent=0.2\times \frac{1}{2}$

After solving

$Horizontalcomponent=0.1T$

Hence the correct option is (B) 0.1 T
