Think of each segment in the diagram as part of a line. Which line appears to be perpendicular to line SP and passes through point R?
K
М.
NO
R
S
Q
P
OPTIONS:RK
RQ
LR
SR

Option (4)

Step-by-step explanation:

Since point R is on the same plane as the line SP has, perpendicular line will have the same plane.

Lines passing through the point R are, KR, RQ and RS.

But the line which is in the same plane as of SP are, RS and RQ.

Perpendicular line to the line SP is line RS only.

Therefore, line perpendicular to line SP and passing through a point R is SR.

Option (4) is the correct option.

step-by-step explanation:

it's is b

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
