Physics Why the needle of iron swims on water surface when it is kept gently ? Due to its shape The density of needle is less than that of water It will remain under the water, when it will displace more water than its weight Due to surface tension Due to its shape The density of needle is less than that of water It will remain under the water, when it will displace more water than its weight Due to surface tension ANSWER DOWNLOAD EXAMIANS APP
