4-2.Friction
medium
આકૃતિમાં દર્શાવેલાં બ્લોક એ $10 \,m / s$ નાં અચળ વેગે જમણી બાજુ તરફ ગતિ કરે છે. સંપર્કમાંની તમામ સપાટીઓ ખરબચડી છે. બ્લોક $B$ પર જમીન દ્વારા લગાડેલું ઘર્ષણ બળ ..... $N$ છે
A$0$
B$20$
C$10$
Dઅપર્યાપ્ત ડેટા
Solution
(b)
(b)
Given that:
velocity of blocks $=10\,ms ^{-1}$
Friction force between $B$ and $A=20\,N$.
As we know,
Force $=$ mass $\times$ acceloration
So, Friction force between the block $B$ and the ground is zero as acceleration of the blocks is zero as they are moving with constant velocity.
