Question

A charged particle (charge = q: mass = m) is rotating in a circle of radius 'R' with uniform speed 'v'. The ratio of its magnetic moment (M) to the angular momentum (L) is ______

पर्याय

• `"q"/(2"m")`

• `"q"/"m"`

• `"q"/(4"m")`

• `(2"q")/"m"`

Answer 1

A charged particle (charge = q: mass = m) is rotating in a circle of radius 'R' with uniform speed 'v'. The ratio of its magnetic moment (M) to the angular momentum (L) is `underline("q"/(2"m"))`.

Explanation:

`"M"/"L" = ("nIA")/("mvr") = "q"/(2"m")`
