Question

17. Combinig Vectors-Magnitude of the resultant In Case A, two vectors of magnitude 6 uints are at right angles to one another. In Case B,four vectors each of magnitude 3 units, are arragned as shown. The outer vectors in Case B are also at right angles to one another, and difference in direction between any pair of adjacent vectors is 30 degress. 45 45° 45 30 30 6 Case A Case B are added together, s the magntidue of the resultant in Case (i) less than, or Cil) equal to the mangitude of the resultant in Case B add O) greater than If all vectors in each case ed tog n your reasoning.

Answer 1

If we make use of the triangular law of vector addition we find that for the case A the resultant, say x, will come out to be 0. Same, happens in the case of the scenario B where the sum of the given vectors all having magnitude 3 will come out be 0. Hence, they are equal to the given case of B.

If we make use of the triangular law of vector addition we find that for the case A the resultant, say x, will come out to be 0. Same, happens in the case of the scenario B where the sum of the given vectors all having magnitude 3 will come out be 0. Hence, they are equal to the given case of B. here, a + x = b 6 + x = 6 x = 0 Therefore, the resultant is coming out to be 0. Same happens, in case B for the given vectors we also get 0.

here,

Therefore, the resultant is coming out to be 0.

Same happens, in case B for the given vectors we also get 0.
