1B is the correct answer.
The direction of a need not be perpendicular to w.
19the symbols are vague: (a) suggests what??? angular acceleration or total linear acceleration??
' the question setter needs to specify this!!!
1ya actually vel vector is tangent to the path......... and v=w/r and here r is a scalar quantity and acc is tangent acc + centripaitla acc ......... tangent acc is along w
