A positively charged particle of mass m and charge q is projected on a rough horizontal x-y plane surface with z-axis in the vertically upward direction. Both electric and magnetic fields are acting in the region and given by vec E = - E_0 hat k and vec B= -B_0 hat k , respectively. The particle enters into the field at (a_0, 0, 0) with velocity vec v = v_0 hat j . The particle starts moving in some curved path on the plane. If the coefficient of friction between the particle and the plane is mu . Then calculate the (a) time when the particle will come to rest (b) distance travelled by the particle when it comes to rest.

There exists a uniform magnetic field vec(B) = +B_(0) hat(k) " for " x gt 0 and vec(B) = 0 for all x lt 0 . A charged particle placed at (0, -a,0) is given an initial velocity vec(v) = v_(0) hat(i) . What is the magnitude and nature of charge on the particle such that it crosses through the origin ? Strategy: When the charge is projected perpendicular to a uniform magnetic field, it follows a circular path. In this case, the force acting on it will be directed either towards +y-axis. or y-axis. It is given that it crosses point O. Thus, the force at (0, -a, 0) must be towards y-axis

A region has a uniform magnetic field B along positive x direction and a uniform electric field E in negative x direction. A positively charged particle is projected from origin with a velocity underset(V)to=V_(0)hati+V_(0)hatj .
