Three stones A, B , C are projected from surface of very long inclined plane with equal speeds and different angles of projection as shown in the figure. The incline makes an angle [tex] \theta [/tex] with horizontal. if [tex] \sf {H_A , H_B and H_C} [/tex] are maximum height attained by A, B and C respectively above inclined plane then choose the Correct choice among them ~

[tex] \sf{H_A + H_C = H_B }[/tex]

[tex] \sf{H_A {}^{2} + H_C {}^{2} } = H_B {}^{2} [/tex]

[tex] \sf H_A + H_C = 2 H_B [/tex]

[tex]\sf H_A {}^{2} + H_C {}^{2} = 2 H_B {}^{2} [/tex]

The resultant of the vectors is [tex]H_A + H_C = H_B[/tex].

What is a resultant vector?

A resultant vector is the vector sum of two or more vectors.

The given vectors;

  • Height of vector A = HA
  • Height of vector B = HB
  • Height of vector C = HC

The height of vector B is the resultant of the three given vectors.

When the vectors are drawn from head to tail, the vector B forms the resultant of the two other vectors (A and C).

Thus, the resultant of the vectors is [tex]H_A + H_C = H_B[/tex].
