In a rectangle ABCD, E is the midpoint
of AB; F is a point on AC such that BF
is perpendicular to AC; and FE
perpendicular to BD. Suppose BC = 8(√3).
Find AB.
The surface between wedge and block
is rough (Coefficient of friction μ).
Find out the range of F such that,
there is no relative motion between
wedge and block. The wedge can move
freely on smooth ground.
A 1 kg block is being pushed against a
wall by a force F = 75 N as shown in
the figure. The coefficient of friction is
0.25. The magnitude of acceleration of
the block is
Find the equation of circle in complex
form which touches iz + z^ + 1 + i = 0
and for which the lines (1 − i)z =
(1 + i)z^ and (1 + i)z + (i − 1)z^ − 4i = 0
are normals.
