Two charges Q_0 and 3Q_0 are at l
distance apart.These two charges
are free to move but do not because
is a third charge nearby.What must
be the charge for the first two to be
in equilibrium?
write the expression of electrostatic force
between two charges Q_(1 ) and Q_2 separated by
distance r. for the following condition
1)in air
2)when die electric present between them
3)when die electric partially fill space betweenp
them
Given the lines
l_1 :−3mx + 3y = 9
and l_(2 ) : y = mx + c
find the value of m and c if
the point (1,2) lie on both lines.
hence the tangent of the
curve y = (mx + c)^2
when it moves across the x−axis
Point charges 88μC,−55μC and
70μC are placed in a straight line.
The central one is 0.75m from
each of the others.Calculate the
net force on each due to the other
two.
Domain of the explicit form of
the function y represented
implicitly by the equation
(1+x)cosy−x^2 =0 is
(a) (−1,1] (b) (−1, 1−(√)5/2]
(c) [1−(√)5/2, 1+(√)5/2]
(d) [0, 1+(√)5/2]
