The radius of a circle is the distance from the center of a circle to any point of a circle.
Explanation:
It is given that,
The position of a particle is given by :
(a) Velocity of a particle is given by :
Putting values,
The acceleration of the particle is given by :
(b) At t = 0,
Velocity, v = 6k m/s
Acceleration, a = 6i m/s²
Answer:
North of East
Explanation:
two forces on the hockey puck is given as
at 15 degree North of East
similarly other force is
at 55 degree North of East
Now net force on the puck is given as
magnitude of force is given as
magnitude of acceleration
direction of acceleration is given as
North of East
Answer:
The electric flux though each face of the cube is 0.0942 Nm²/C.
Explanation:
The expression for the electric flux through the cuboid is given by:
Since, area of cuboid = 6a²
Where,
E is the electric field
a is the side of the cuboid
q is the charge
is the constant having value 8.85×10⁻¹² C²/Nm²
Thus, the expression for the electric flux through one face of the cuboid is given by:
So,
Given ,
q = 5.0×10⁻¹² C
Solving,
<u>The electric flux though each face of the cube is 0.0942 Nm²/C.</u>
