A body of mass 10 kg is moving eastward ...

A body of mass 10 kg is moving eastward with a uniform speed of 2 m `s^(-1)`. A force of 20 N is applied towards north. What is the magnitude of displacement after 2 seconds?.

A

4m

B

8m

C

4`sqrt2` m

D

`8sqrt2`m

Text Solution

Verified by Experts

The correct Answer is:
C
Displacement towards east = x = 4m
Accleration towards north= `("force")/("mass")=2ms^(-2)`
Displacement towards north=`y=1/2at^2=4m`
Net displacement = `sqrt(x^2=y^2)=4sqrt2m`
