An object is moving along the positive X-axis with the uniform velocity of 5 ms–1. Then
The net force must be along the positive X-axis
The net force must be zero
The net force must be along the negative X-axis
The net force is a non-zero constant

Answer:
Correct option is
B
Negative z-axis
The velocity of electron
v
is along (+x) axis. The
E
field applies a force along (−y) axis . In order to have ∑
F
=0 on the electrons
B
field must apply force in +y) axis
As Lorintz force expersion
F
m
=l(
V
×
B
).
F
m
along (+y)
thus we get
B
should be along (−z) axis

Given : An object moving in uniform velocity =5 m/s
To Find : Net Force on object.
Solution :
If an object is moving with a uniform velocity, then it's acceleration is zero.
Thus,
Force acting on the body F = ma
where
m is the mass of the object
a is the acceleration of the object
As the acceleration is zero,
The net force acting on the body is zero.
Hence, The net force must be zero.
