A uniform square plate S (side c) and a uniform rectangular plate R (sides b,a) have identical areas and masses (show in the figure). Show that I_(zR //I_(zS) > 1

A uniform square plate has a small piece Q of an irregular shape removed and glued to the enre of the plate leaving a hole behind shown in the figure. The moment of inretia about the z-axis is then

A uniform square plate has a small piece Q of an irregular shape removed and glued to the enre of the plate leaving a hole behind shown in the figure. the CM of the late is now in the following quadrant of x-y plane.

Through A,B and C lines RQ,PR and QP have been drawn, respectively parallel to sides BC, CA and AB of a triangleABC as shown in fig. show that BC=1/2QR

Nazma's sister also has a trapezium shaped plot.Divide it into three parts a s shown in the figure.Show that the area of trapezium WXYZ=(h(a+b))/x

A point charge +10muC is at a distance 5 cm directly above the centre of a square of side 10 cm as show in the figure. What is the magnitude of the electric flux through the square?

A particle of mass m and charge (-q) enters the region between the two charged plates initially moving along x-axis with speed v_x. The length of plate is L and an uniform electric field E is maintained between the plates. Show that the vertical deflection of the particle at the far edge of the plate is qEL^2//(2m v_x^2) .

If in a triangle A B C , the side c and the angle C remain constant, while the remaining elements are changed slightly, using differentials show that (d a)/(c sA)+(d b)/(cosB)=0

A rectangular loop has a sliding connector PQ of length l and resistance R. It is moving with a speed v as shown in the figure. The set up is placed in a uniform magnetic field goping into the plane of the paper. The three currents I_1 , I_2 and I are
