L1 तथा L2 संक्षेप में

Five balls L1, L2, L3, L4 and L5 are kept one above the other (not necessarily in the same order). L1 is just above L5 and just below L4. L2 is just above L3 and just below L5. How many balls are above L2? पांच गेंदों L1, L2, L3, L4 और L5 को एक के ऊपर एक रखा जाता है (जरूरी नहीं कि उसी क्रम में)। L1, L5 के ठीक ऊपर और L4 के ठीक नीचे है। L2, L3 के ठीक ऊपर और L5 के ठीक नीचे है। L2 के ऊपर कितनी गेंदें हैं?

L1-L3

L1-L4

In the figure given below there are two convex lenses L1 and L2 having focal lengths F1 and F2 respectively. The distance between L1 and L2 will be

In Fig., there are two convex lenses L_1 and L_2 having focal lengths F_1 and F_2 respectively. The distance between L_1 and L_2 will be : .

ABCD is a square of length a, a in N, a > 1. Let L_1, L_2 , L_3... be points on BC such that BL_1 = L_1 L_2 = L_2 L_3 = .... 1 and M_1,M_2 , M_3,....be points on CD such that CM_1 = M_1M_2= M_2 M_3=... = 1. Then sum_(n = 1)^(a-1) ((AL_n)^2 + (L_n M_n)^2) is equal to :

Let L_1 and L_2 be the lines whose equation are (x-3)/3=(y-8)/-1=(z-3)/1 and (x+3)/--3=(y+7)/2=(z-6)/4 and respectively. A and B are two points on L_1 and L_2 respectively such that AB is perpendicular both the lines L_1 and L_2. Find points A, B and hence find shortest distance between lines L_1 and L_2

The voltage-current graphs for two resistor of the same meterial and the same radius with lengths, L_1 and L_2 are shown in fig 5.2. if L_1 gt L_2 , state with reason which of these graphs represents votage- current change of L_1.
