MODULE 6 IQ 1

Question 1

The force experienced by a charge due to an electrification field is given by:

Answer 1

F = qE

E: electric field strength (N/C)
Q: charge of object experiencing the force (C)
F: force acting on charged particle (N)

Question 2

Electric field strength between parallel plates:

Answer 2

E = V/d

E: electric field strength (Vm^-1)
V: potential difference (V)
D: distance between electric field plates (m)

Question 3

The work done in an electric field is given by:

Answer 3

W = qEd Or W = qV

W: work (J)
Q: magnitude of charge (C)
E: electric field strength (V/m)
D: distance between points, parallel to the electric field (m)
V: electric potential (V or VC)

Question 4

If a charge moves against the electric field

Answer 4

Work is done onto the field by the charge

Question 5

If a charge moves along the electric field

Answer 5

Work is done by the field onto the charge

Question 6

Charged particles in magnetic fields

Answer 6

F= qVBsinθ

F: force acting on the charge exerted by the magnetic field (N)
Q: charge (C)
V: velocity of charged particle (m/s)
B: magnetic field strength (T)
θ: angle bet5ween the magnetic field and direction of charged particle
