A boat is moving with a velocity $3i + 4j $ with respect to ground. The water in the river is moving with a velocity $-3i -4j $ with respect to ground. The relative velocity of the boat with respect to water is

A$8j$

B$-6i -8j$

C$6i +8j$

D$5\sqrt 2 $

Solution

(c)Relative velocity $= (3i + 4j) -(-3i -4j) = 6i + 8j$
