Answer :
Answer:
Explanation:
Magnetic Force on the rod F = Bi L
Work done by this force = F X d
= Bi Ld
This energy is converted into both rotational and linear kinetic energy
= 1/2 I ω² + 1/2 mv²
= 1/2 x 1/2 m r²ω²+ 1/2 mv²
= 1/4 m v² + 1/2 mv²
= 3/4 mv²
So according to conservation of energy
Bi Ld = 3/4 mv²
v = [tex]\sqrt{\frac{4BiLd}{3m} }[/tex]
