a magnetic moment of U = 1 (i) + 2 (k) , surrounded by a magnetic uniform field of B= 3 (i) + 4 (j) - 1 (k)
find the potential energy in mJ ?
dot product of 2 vectors
( ui*bi)+(uj*bj)+(uk*bk) =
or finding the module of both vector and doing AB cos theta
but we would need to find the angle between the 2 vectors with the formula u*B / uB so dot product over product of both modules
3. The attempt at a
dot product of u and b ,so the answer should be 11.4 or 5,39 (539) ,
