Two blocks are placed on a smooth
horizontal surface and connected by a
string pulley arrangement as shown.
If a force F starts acting on block m_1 ,
then find the relation between acceleration
of both masses and their values
A thin bi − convex lens rest on a plane mirror . it is found that a point
objects placed 20cm above the object coincide with it own image.
Determine the position and nature of the image when the object is placed
(i) 8cm and (ii) 12 from the lens mirror combinatiom
STATEMENT-1 : The graph between
kinetic energy and vertical displacement
is a straight line for a projectile.
STATEMENT-2 : The graph between
kinetic energy and horizontal
displacement is a straight line for a
projectile.
STATEMENT-3 : The graph between
kinetic energy and time is a parabola
for a projectile.
Parallel tangents to a circle at A
and B are cut in the points C and D
by a tangent to the circle at E.
Prove that AD, BC and the line
joining the middle points of AE
and BE are concurrent.
Let AC be a line segment in the plane
and B a point between A and C.
Construct isosceles triangles PAB and
QBC on one side of the segment AC
such that ∠APB = ∠BQC = 120° and
an isosceles triangle RAC on the other
side of AC such that ∠ARC = 120°.
Show that PQR is an equilateral
triangle.
