Question

which of the following complex is more stable and why
[Fe(CN)6]³- or [Fe(CN)6]⁴-​

Answer 1

Explanation:

MAGNETIC FORCE ( F ) = 31.25 × 10-⁴ N

OPTION 4

Explanation:

★ MAGNETIC FORCE ★

★ GIVEN ;

» Current in Wire ( i ) = 5 A

» Length of Wire ( L ) = 5 cm

» Magnetic Field ( B ) = 2.5 × 10-² T

» Angle Made by Wire with Magnetic Field ( ∅ ) = 30°

★ MAGNETIC FORCE ( F ) = ???

____ [ BY USING FORMULA ] ____

[ F \: = \: i \: \times \: L \: \times \: B \: \times \: \sin( \alpha ) ]F=i×L×B×sin(α)]

★ F = i × L × B × Sin 30°

» F = 5 × ( 5 × 10-² × 2.5 × 10-² )× 1 / 2

» F = 62.5 × 10-⁴ × 1 / 2

★ MAGNETIC FORCE ( F ) =

31.25 × 10-⁴ N ★

[ ✓ NOTE :- FORCE ON WIRE KEPT IN SOLENOID IS INDEPENDENT OF NO. OF TURNS OF COIL AND IT'S RADIUS ✓ ]

______________________________________

ANSWER :- MAGNETIC FORCE ON CURRENT CARRYING WIRE IN SOLENOID IS ;

★ F = 31.25 × 10-⁴ N ←

[ OR ]

★ F = 3.125 × 10-³ N ←
