(Positive, Negative, Uncharged) Particle 2 is __________.
(Positive, Negative, Uncharged) Particle 1 is __________.
(Positive, Negative, Uncharged) Particle 4 is __________.
(Positive, Negative, Uncharged) Particle 5 is __________.
(Positive, Negative, Uncharged) Particle 3 is __________.

Explanation / Answer

By ight hand thumb rule

Put your first finger in the direction of the magnetic field. Put your thumb in the direction of the velocity of the particle (just choose a point on its path). If your second finger (or palm, whatever you prefer) is sticking outward from the circle, then the charge is negative. The right hand rule works for positive charges; so when the charge is negative, you get the opposite of what the force really should be

2.The palm is positive ,the palm is poinitng inwards

1.Uncharged. There no effect on it (it
