Question

if a vector is along horizontal direction its vertical component is​
a)maximum
b)minimum
c)zero
d)none of these

Answer 1

if a vector is along the horizontal direction is vertical component is equal to zero.

Option C

Explanation:

• the angle which is made by the horizontal direction and the vertical direction is equal to 90 degree. if we consider the value of a vector in horizontal direction is equal to X then the vertical component will have the value of, x cos a , where a is the angle between the horizontal and vertical direction that is 90° .
• Hence the magnitude will be  equal to zero. Since the value of cos 90 is zero

Answer 2

Vector is along horizontal direction its vertical component

Explanation:

• The answer is zero "C" option.
• The angle made by horizontal and vertical direction is equal to 90 degree.
• Suppose the value of vector in horizontal direction is equal to the x
• The vertical component have the value will be x cos a
• A is considered the angle between vertical and horizontal action that is called 90 degree.
• Thus the magnitude will be zero and value of cos 90 will be zero.
