Two long straight wires are connected by a circular section which has a radius R .All the three segments lie in the same plane and carry a current I. The magnetic induction at the centre O of the circular segments is

Two long straight conductors with currents and are along X and Y axes. The equation of locus of points of zero magnetic induction is

Figure shows a coil of radius 2 cm concentric with a coil of radius 7 cm Each coil has 1000 turns with a current of 5 A. In larger coil, then the current needed in the smaller coil to give the total magnetic field at the centre equal to 2 mT is

In the given figure the magnetic induction at the point O is

A current IA is flowing in the sides of equilateral triangle of side m The magnetic induction at centroid of the triangle is

The magnetic field at the centre of circular loop in the circuit shown below is

Is this quadrilateral a trapezoid?

A thin 50 cm long metal bar with mass 750 g rests on, but is not attached to two metallic supports in a uniform 0.45T magnetic field as shown in Fig .A battery and a 25resistor in series are connceted to the supports. The largest voltage the battery can have without breaking the circuit at the supports (units are in ”V”) is

What is the area of the trapezoid?

The radius of a circle is 7 meters. What is area of the circle?

Multiply: 9 × 4 = 

Solve the quadratic equation below using the Quadratic Formula $x^2+5x-14=0$

In the figure, If AC = 75 cm AB = 100 cm and BD = 1.25 cm then AD = 

we can use the property that ratio of sides remains same in similar triangles.

we can use the property that ratio of sides remains same in similar triangles.

In the figureand areaThe value of

In the figure, , AB = 9 cm, AD = 7 cm, CD = 8 cm and CE = 10 cm Then DE = ?

if 2 angles are same in a triangle, then the triangles are similar. we can use the property that ratio of sides remains same in similar triangles.
