Question

Two infinitely long linear conductors are arranged perpendicular to each other and are in mutually perpendicular planes as shown in figure. If $I subscript 1 end subscript equals 2 A$ A along the y–axis and $I subscript 2 end subscript equals 3 A text along end text minus v e z minus a x i s text and end text A P equals A B equals 1 c m$ . The value of magnetic field strength $stack B with rightwards arrow on top$ at P is

$(3 \times 10^{- 5} T) \tilde{j} + (- 4 \times 10^{- 5} T) \tilde{k}$
$(3 \times 10^{- 5} T) \vec{j} + (4 \times 10^{- 5} T) \bar{k}$
$(4 \times 10^{- 5} T) \tilde{j} + (3 \times 10^{- 5} T) \hat{k}$
$(- 3 \times 10^{- 5} T) \tilde{j} + (4 \times 10^{- 5} T) \bar{k}$

The correct answer is: $open parentheses 3 cross times 10 to the power of negative 5 end exponent T close parentheses stack j with rightwards arrow on top plus open parentheses 4 cross times 10 to the power of negative 5 end exponent T close parentheses stack k with bar on top$

A mass spectrometer is a device which select particle of equal mass. An iron with electric charge $q greater than 0 blank$ starts at rest from a source S and is accelerated through a potential difference V. It passes through a hole into a region of constant magnetic field $stack B with rightwards arrow on top$ perpendicular to the plane of the paper as shown in the figure. The particle is deflected by the magnetic field and emerges through the bottom hole at a distance d from the top hole. The mass of the particle is
