Answer:
Explanation:
Using:
Force = electric field * charge
Force = magnitude of charge * velocity * magnetic field * sin tither
Force on particle due to electric field:
Force on particle due to magnetic field:
is in the positive x direction as
is in the negative x direction while net force is in the positive x direction.
Magnetic field is in the positive Z direction, net force is in the positive x direction.
According to right hand rule, Force acting on particle is perpendicular to the direction of magnetic field and velocity of particle. This would mean the force is along the y-axis. As this is a negatively charged particle, the direction of the velocity of the particle is reversed. Therefore velocity of particle, v, has to be in the negative y direction.
Now,
Explanation:
Given that,
Initial speed of a car, u = 12 m/s
Aceleration, a = -1.6 m/s²
(a) The displacement of car after 6 seconds is :
(b) The displacement of the car after 9 seconds is :
Hence, this is the required solution.
