Answer:
Explanation:
The electric field applies a force qE, but only in the y direction. This means that the x component of the
momentum must be conserved:
0 = Fx =dpx/dt
=⇒ px is conserved
pxi = γimvxi = pxf = γfmvxf (see the attactments)
the particle will acquire a velocity in the y
direction, and vxf <vxi. The x-component of the velocity, and thus the x-component of the momentum
must decrease.
Answer:
The horizontal displacement is
Explanation:
From the question we are told that
The angle at which the string is maintained is
The length of string reeled in is
Using the SOHCAHTOA formula
We have that the hypotenuse(Hyp) is l = 152
Hence the horizontal displacement of the kite which is the Adjacent(Adj) can be evaluated as
substituting values
=>
