Find the force experienced by the wire carrying a current 2A if the ends P and Q of the wire have coordinates (1,2,-3) m and (-2,-5,1)m respectively when it is placed in a magnetic field `B=(hati+hatj+hatk)T`

Text Solution

Verified by Experts

The force acting on the wire is
`vecF=vec(iR_(21))xxvecB`
`=i(vecr_(2)-vecr_(1))xxvecB`
`=2(-3hati-7hatj+4hatk)xx(hati+hatj+hatk)`
`=2(-11hati+7hatj+4hatk)N`
