A conductor carries a current of 20 A and is at rightangles to a magnetic field having a flux density of 0.9 T. If the length of the conductor in the field is 30 cm, calculate the force acting on the conductor. Determine also the value of the force if […]

Q1. Some dogs have erect ears; others have drooping ears. Some dogs bark while following a scent; others are silent. Erect ears and barking are because of dominant alleles located on different chromosomes. A dog homozygous for both dominant traits is mated to a droopy-eared silent follower.
