A proton moving with a velocity of `2xx10^(6)ms^(-1)` describes circle of radius `R` in a magnetic field. The speed of an `alpha-` particle to describe a circle of same radius in the same magnitude field is

A proton moving with a velocity of 2 xx 10^6 ms^-1 describes a circle of radius R in a magnetic field. The speed of an alpha -particle to describe a circle of same radius in the same magnetic field is

A proton carrying 1 MeV kinetic energy is moving in a circular path of radius R in uniform magnetic field. What should be the energy of an alpha- particle to describe a circle of the same radius in the same field?

A proton carrying 1 MeV kinetic energy is moving in a circular path of radius R in unifrom magentic field. What should be the energy of an alpha- particle to describe a circle of the same radius in the same field?

A proton carrying 1 MeV kinetic energy is moving in a circular path of radius R in unifrom magentic field. What should be the energy of an alpha- particle to describe a circle of the same radius in the same field?

A proton describes a circle of radius 1 cm in a magnetic field of strength 0.10 T. What would be the radius of the circle described by an a-particle moivng with the same speed in the same magnetic field?

A proton describes a circle of radius 1 cm in a magnetic field of strength 0.10 T. What would be the radius of the circle described by an a-particle moivng with the same speed in the same magnetic field?

A proton describes a circle of radius 1 cm in a magnetic field of strength 0.10 T .What would be the radius of the circle described by an deuteron moving with the same speed in the same meagnetic field?

A doubly ionised He^(+2) atom travels at right angles to a magnetic field of induction 0.4T with a velcoity of 10^(5)ms^(-1) describing a circle of radius r . A proton travelling with same speed in same direction in the same field will describe a circle of radius.
