Question

Magnitude of vector which comes on addition of two vectors, 6i+ 7j and 3i+4j is​

Answer 1

Answer:

√202

Explanation:

Magnitude of vector which comes on addition vectors of 6 i + 7 j and 3 i + 4 j is?

Let A = 6 i + 7 j and B = 3 i + 4 j

A + B = 9 i + 11 j

So magnitude of A + B is

| A + B | = ( 9² + 11² )½ = (81+ 121)½= √202
