Hi, Before answering the question, i want to make a comment to find the direction in cross product. One can use any method to find dire tion of cross product but for a person like me, usually forgot the naming to fingers in Fleming left hand or right hand rule. Here is a General Right hand rule to find the direction of cross product appear anywhere in physics. The method is, For( A cross B)stretch ur right hand such that your fingers allign in direction of first vector(A) and your palm is toward the second vector (B) then the thumb will show the direction of cross product. we're going to use this rule to solve our problem. pls see the attachment.
