distance between charges
both A and B
medium between two charges
1 pico farad (1pF) is equal to
1×10-9F
1×10-12F
1×10-6F
1×10-10F
Two charges are placed at a certain distance. If the magnitude of each charge is doubled the force will become
1/4th of its original value
1/8th of its original value
4 times of its original value
8 times of its original value
If an electrons is allowed to move along the field in a non uniform electric field then it will follow
Spiral path
Straight line
Curved path
Circular path
If F is force acting on test charge qo, electric field intensity E would be given by
E = F - qo
E = F/qo
E = F + qo
E = qo/F
Property of material due to which it attracts or repels other objects is
friction
velocity
current
charge

5 × 109 Nm²C-2
7 × 109 Nm²C-2
8 × 109 Nm²C-2
9 × 109 Nm²C-2
Charge on capacitor plates is directly proportional to
current
electric field intensity
potential difference
resistance
A capacitor holds 0.03 C of charge when fully charged by a 6V battery. To hold 2C of charge, voltage required would be
150V
100V
300V
400V
When we rub a glass rod with a silk cloth then
glass rod acquires negative charge while silk acquires positive charge
glass rod acquires positive charge while silk acquires negative charges
both glass rod and silk acquire negative charge
both glass rod and silk acquire positive charge
If mica sheet is placed between the plates of a capacitor the capacity
increases
decreases
increases then decreases
decreases then increases
