Answer:

Here,

Horizontal component, straight B subscript straight H space equals space 0.4 space cross times space 10 to the power of negative 4 end exponent straight T

Angle of dip, straight delta space equals space 45 to the power of straight o

Using the formula, box enclose straight B subscript straight V over straight B subscript straight H space equals space tan space straight delta space end enclose

Putting values, we get

straight B subscript straight V space equals space straight B subscript straight H space tan apostrophe straight delta

straight B subscript straight V space equals space 0.4 space cross times space 10 to the power of negative 4 end exponent space tan space 45 degree

straight B subscript straight V space equals space 0.4 space cross times space 10 to the power of negative 4 end exponent straight T

which is the required vertical component of Earth's magnetic field.

Using the below formula we can find the value of resulatant magnetic field.

box enclose straight B subscript straight H space equals space straight B subscript straight E space cos space straight delta space end enclose

space space space straight B subscript straight E space equals space fraction numerator straight B subscript straight H over denominator cos space straight delta end fraction

straight B subscript straight E space equals space fraction numerator 0.4 space cross times space 10 to the power of negative 4 end exponent over denominator cos space 45 degree end fraction space

space space space space space equals space 0.4 square root of 2 space cross times space 10 to the power of negative 4 end exponent straight T

straight B subscript straight E space equals space 0.5656 space cross times space 10 to the power of negative 4 end exponent straight T.
