QAIPM-2000-Ph-2999: NEET 2000 Physics - Class 11 AIPM-2000-Ph-2999 Solution: If \( {F}=(60 {i}+15 {j}-3 {k})\) N and \( {v}=(2 {i}-4 {j}+5…

\vec{F}=(60\hat{i}+15\hat{j}-3\hat{k})

N and

\vec{v}=(2\hat{i}-4\hat{j}+5\hat{k})

m/s, then instantaneous power is

Step-by-Step Verified Solution

P = F _ . v _ = ( 60 i ^ + 15 j ^ _ 3 k ^ ) . ( 2 i ^ _ 4 j ^ + 5 k ^ ) = 120 � 60 � 15 = 45 watts.
