For PLANE mirror,
v = -u
Diff it wrt time, we get:
Vel. of Image wrt mirror = - Vel. of object wrt mirror
⇒V(i,m) = -V(o,m)
[V(i)-0] = - [ 50-(0)]
V(i)= -50 cm/sec..
V IMAGE wrt OBJECT = V(i)-V(o)
=-50-50=-100 cm / sec
v = -u
Diff it wrt time, we get:
Vel. of Image wrt mirror = - Vel. of object wrt mirror
⇒V(i,m) = -V(o,m)
[V(i)-0] = - [ 50-(0)]
V(i)= -50 cm/sec..
V IMAGE wrt OBJECT = V(i)-V(o)
=-50-50=-100 cm / sec
Hope u understood it..
hey
wrt and diff means
wrt means with respect to and diff means differentiate
ok
hey I marked you as brainlist
are u in class 10?...thnx btw
yes
