70-10/70 x 100 percentage change ....
60/70, 6/7 fract change
Assuming this is an elastic collision, they go in the direction of the object with more mass
Answer:
Acceleration of proton will be
Explanation:
We have given a proton is placed in an electric field of intensity of 700 N/C
So electric field E = 700 N/C
Mass of proton
Charge on proton
So electric force on the proton
This force will be equal to force due to acceleration of the proton
According to newton's law force is given by F = ma
So
So acceleration of proton will be
Short Answer- Friction
Explanation- There is friction between the grass and the ball. Friction is a type of force that limits motion between two surfaces that are touching. Friction is the force that one surface exerts on another with the two surfaces rubbing together.
This is the answer, hope it helps :)
