1) cos(200π – π/3)
will be in 4th quadrant
cos(200π – π/3) = cos(–π/3)
= cos π/3 =
2)
According to graph
tan θ = = 2
Slope m = –2
c=+4
⇒ y = –2x + 4
⇒ y + 2x = 4
3)

5)
From O to A acute angle is increasing so slope is increasing and from A to B angle is decreasing so
slope will decrease.
6) 4 – 2cosθ

Here, for maximum value
use cosθ = –1

Newton's first law defines force. Newton's second law gives us a measure of force. Impulse gives us
the effect of force. Recoiling of gun is accounted for by Newton's 3rd law.
16)
Momentum acquired by the particle is numerically equal to area enclosed between the F-t curve and
time axis. For the given diagram area in upper half is positive and in lower half is negative (and
equal to upper half), so net area is zero. Hence the momentum acquired by the particle will be zero.

body becomes neutral.

q1 : q2 = 1 : 9, L = 1 metre
So the required point is at a distance of 0.25 m from the charge 1 × 10–9 coul or 0.75 m from the
charge 9 × 10–9 coul.
25)
Charges are same or different, electric force remains same, (due to reaction law) but gravitational
force acts indivisually. So if masses are differnt m 1 g and m 2 g are different so, angles becoes
different, if m1 < m2 then θ1 > θ2.

Let y =

y2 – 2 =
y2 – 2 = 2 cos 2θ
y2 = 2[1 + 2 cos2θ – 1]
y = 2cosθ

y = 3x2 – 4
y = kx2 – c
