PhysicsSingle correct+4 / -1Question 12 of 90

A triangular shaped wire carrying 10 A current is placed in a uniform magnetic field of 0.5 T, as shown in figure. The magnetic force on segment CD is

(Given BC = CD = BD = 5 cm.)

A wire ABCDE along a horizontal line with an equilateral bump BCD (side 5 cm); the magnetic field points horizontally to the right, along AE.

0.126 N

0.312 N

0.216 N

0.245 N

Answer and worked solution

Official answer: C

Force on CD. $F=IlB\sin60^\circ=10\times0.05\times0.5\times\frac{\sqrt3}2=0.216$ N.

(C)
