Q1 If a charge particle moves perpendicular to a magnetic field, then, which of the following is true
- (a) Speed of the particle is changed.
- (b) Speed of the particle remains unchanged.
- (c) Direction of the particle remains unchanged.
- (d) Acceleration of the particle remains unchanged.
- (b) Speed of the particle remains unchanged.
Q2 The path of an electron in a uniform magnetic field may be
- (a) Circular but not helical
- (b) Helical but not circular
- (c) Neither helical nor circular
- (d) Either helical or circular
- (d) Either helical or circular
Q3 Direction of magnetic field due to a current carrying circular coil can be determined by which rule?
- (a) Right hand thumb rule
- (b) Right hand Rule
- (c) Left hand rule
- (d) All of these
- (a) Right hand thumb rule
Q4 An electric charge 'q' moves with a constant velocity 'v' parallel to the uniform magnetic field 'B' , then force experienced by the charge is :
- (a) qvB
- (b) B/qV
- (c) Zero
- (d) qv/B
- (c) Zero; Force on a charged particle moving in magnetic field is qvBsinθ as charge is moving parallel θ =0 therefore F=0
Q5 A charge in electric field always experience a force.
- (a) True
- (b) False
- a)True
Q6 A stationary charge does not experience any force in magnetic field.
- (a) True
- (b) False
- (a) True
Q7 Electric field exerts force on both stationary and moving charges.
- (a) True
- (b) False
- (a) True
Q8 The force is maximum, when the charge move ......... to the direction of magnetic field.
- (a) `90^{0}`
- (b) `45^{0}`
- (c) parallel
- (d) All of these
- `90^{0}` ; F = qvB Sinθ ,θ =`90^{0}` , F will be maximum
Q9. Path of a charge moving inside a magnetic field in transverse direction will be
- (a) Circular
- (b) Rectangular
- (c) Straight line
- (d) Parabolic
- a) Circular
Q10 If a charged particle moves inside the magnetic field , magnitude of which quantity is not effected by the magnetic field
- (a) Force
- (b) Velocity
- (c) Frequency
- (d) Time period
- (b) Velocity
