bar l construction

Draw a line through E parallel to p intersecting l in G, n in H respectivel..

When free space is the communication channel, antennas radiate and receiver the signal. Theory shows that the antennas operate effective only when their dimensions are of the order of the magnitude of wavelength of the signal being transmitted...

Consider a point P located on the axial line of a short bar magnet of magnetic length '2l' and pole strength m. Let us find at a point p which is at a distance d from the centre of the magnet. Magnetic flux density at p due to N-pole ..

Are the points I, L, J, and G coplanar? What is the intersection of IL ‾ and plane IJGH? => Yes, L or Yes, I or No, I or No, J..

Let P be a point on the equatorial line of a short bar magnet where flux density due to the magnet is to be found out. SN = 2l, Magnetic flux density at p due to N-pole is ..

ΔABC is isosceles, D is the midpoint of side BC ‾ as shown. What is the reflection image of C under the line l ? => B or D or A or C itself..

A box contains four types of pens: Type 1, Type 2, Type 3 and Type 4. Construct a bar graph to represent the number of pens in each type. What percent of the total number of pens belong to Type 2? Type 1 2 3 4 Number of pens 13 8 9 10 => Graph 4; 20% or Graph 2; 25% or Graph 1; ..

Tangents drawn from an external point P touch a circle of radius( r ) 20 cm at points L and M making an angle of 60 o with each other. The length of LM ‾ is => 10 3 cm or 20 cm or 20 3 cm or 10 cm..

A is a point on a line l and its reflection image in l is A′ .Which of the following is correct? => A = A′ or A′ lies on line l or l is the perpendicular bisector of AA′ ‾ or A ≠ A′..

In triangles GHI and JKL, HI ‾ ≅ KL ‾ , GI ‾ ≅ JL ‾ , ∠ I ≅ ∠ L ; ΔHGI is congruent to =>ΔJKL or ΔKLJ or ΔLKJ or ΔKJL..
