Question

The plane of a 3.0 cm

Answer 1

Width = w = 3.00 cm = 0.03 m

Height = h =6.00 cm = 0.06 m

Area =A = hw= 0.03*0.06 =1.8*10^-3 m^2

Total length = L = 2(h+w)

Total length = L =2(0.06+0.03)

Total length = L ==0.18 m

For given perimeter , a circle has largest area

If radius of circle is 'r'

Perimeter = 2(pi)r=length of wire =L=0.18 m

Radius = r =0.18 /2(pi)

Radius = r =0.02864 m

Area of circle = pi*r^2

Area of circle = 0.002578 m^2

Current = A = 6.10 A

Maximum Magnetic Moment of circular loop=pm =current *area of circle

Maximum Magnetic Moment of circular loop =6.1*0.002578

Maximum Magnetic Moment of circular loop =0.01572 Am^2

Magnetic field = B = 0.160 T.

The maximum torque on the loop = t = pmxB

The maximum torque on the loop = t = (0.0157)*0.16

The maximum torque on the loop = t =2.512
