Consider a vector F→=4i^−3j^.\overset{\rightarrow}{F} = 4\widehat{i} - 3\widehat{j}. Another vector that is perpendicular to F→\overset{\rightarrow}{F} is

A

(a) 4i^+3j^4\widehat{i} + 3\widehat{j}

A

(b) 6i^6\widehat{i}

A

(c) 7k^7\widehat{k}

A

(d) 3i^−4j^3\widehat{i} - 4\widehat{j}

Explanation

Solution

(c)

Sol. Force F lie in the x-y plane so a vector along z-axis will be perpendicular to F.
