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 `vec(B)=(hat(i)+hat(j)+hat(k))T`

Text Solution

Verified by Experts

The force acting on the wire is `vecF = vec(ir_21) xx vecB`

` = i (vecr_2 - vecr_1) xx vecB`
` = 2 (-3 hati -7 hatj + 4hatk) xx (hati + hatj + hatk)`
` = 2 (-11 hati + 7 hatj + 4 hatk) N`
