2 Marks

VSAQ-1 : When two right angled vectors of magnitude 7 units and 24 units combine, what is the magnitude of their resultant?

The magnitude of the resultant vector when two right-angled vectors of 7 units and 24 units combine is 25 units.


VSAQ-2 : Two forces of magnitudes 3 units and 5 units act at 600 with each other. What is the magnitude of their resultant?

The magnitude of the resultant force when two forces of 3 units and 5 units act at an angle of 60 degrees with each other is approximately 5.83 units.


VSAQ-3 : If A = (i) + (j). What is the angle between the vector A and X-axis?

The angle between vector A and the X-axis is 45 degrees.


VSAQ-4 : If P = 2i +4j +14K and Q = 4i +4j +10K find the magnitude of P +Q.

The magnitude of P + Q is approximately 11.53 units.


VSAQ-5 : What is the acceleration of a projectile at the top of its trajectory?

The acceleration of a projectile at the top of its trajectory is approximately 9.81 m/s² in the downward direction due to gravity.


VSAQ-6 : The vertical component of a vector is equal to its horizontal component. What is the angle made by the vector with x-axis?

The angle made by the vector with the x-axis is 45 degrees when the vertical component of the vector is equal to its horizontal component.


VSAQ-7 : Write the equation for the horizontal range covered by a projectile and specify when it will be maximum.

The equation for the horizontal range (R) covered by a projectile is:

R = (u^2 * sin(2θ)) / g

Where:

  1. u is the initial velocity of the projectile.
  2. θ is the launch angle.
  3. g is the acceleration due to gravity (approximately 9.81 m/s²).

The horizontal range will be maximum when the launch angle (θ) is 45 degrees.
