1 ) P and Q are two charges of charge + 2 uC and - 2 uC respectively . So Electric field at point Z is ?
A ) zero , B
) non - zero ,
C ) infinite , D ) None of these ,
Correct
answer : - B ) non - zero ,
Because
both charges have Same magnitudes . So
Voltage between them is zero and
electric field between them at point Z is non - zero .
2 ) E = ∆V / d .
∆V =
potential difference .
E =
Electric field .
d =
distance .
3 ) If electric field at a point is zero , so
potential difference at a same point will be . . . . . . . . . . . . . . . ,
A ) zero , B )
non zero ,
C ) infinite , D ) None of these .
Correct
answer : - B ) non zero ,
if
electric field is zero , at same point potential difference will not be zero
and vice versa .
4 )
When a plate is earthened , so its potential difference becomes . . . . . . . .
. . . . . . . ,
A ) equal to zero , B ) infinite ,
C ) non zero , D ) None of these .
Correct
answer : - A ) equal to zero ,
5 )
In projectile motion , horizontal force is . . . . . . . . . . . . ,
A ) constant ,
B )
uniform ,
C ) variable , D ) None of
these .
Correct
answer : - A ) constant ,
So
object will have acceleration in downwards direction .
6 )
If an electron is entering in an electric field as shown , so it will deflect
or not ?
A ) deflect towards positive plate ,
B ) deflect towards negative plate ,
C ) remains undeflected ,
D ) None of these .
Correct
answer : - A ) deflect towards positive
plate ,
